Gelukkige gesin
‘n Gesinseenheid wat wérk word deur vyf eienskappe gekenmerk, skryf Gary Chapman in sy boek The Family You’ve Always Wanted.
Wen-gesinne is gesinne wat dien; bestaan uit ’n ma en pa wat ’n premie plaas op intimiteit; ouers het wat lei; kinders het wat hul ouers eer en gehoorsaam en pa’s het wat leiding neem en lief is vir hul gesinne.
Gesinne wat dien
In enige gesin is daar werk wat gedoen moet word, sê Chapman. Klere moet gewas en gestryk word, beddens moet opgemaak word en asblikke moet leeggemaak word. En hoewel daar eksterne hulp beskikbaar is vir besige gesinne, moet elke gesinslid steeds ’n taak verrig, want ’n gesonde gesin het volgens Chapman ’n “ingesteldheid om ander lede van die gesin en die gemeenskap te dien”.
Intimiteit
Wanneer jy trou, sê jy “ja” om jou lewe met iemand te deel en gemeenskaplike drome en geluk na te streef.
Chapman sê wanneer verliefdheid verflou, verloor baie paartjies intimiteit. Verskillende idees oor intimiteit skep ook probleme omdat ’n man dalk hunker na seksuele intimiteit en ’n vrou na emosionele intimiteit.
Intimiteit stam van die Latyn intimus, wat “binneste” beteken. Chapman sê intimiteit gebeur wanneer twee mense hul binneste vir mekaar oopmaak. Jy verkry ook nie bloot intimiteit en behou dit nie – dit is iets waaraan jy voortdurend moet werk.
In sy boek verduidelik hy vyf maniere hoe jy verskillende soorte intimiteit kan verkry:
Sê wat jy dink – intellektuele intimiteit;
Bespreek jou gevoelens – emosionele intimiteit;
Bring saam tyd deur en gesels oor die tye wanneer julle nie bymekaar is nie – sosiale intimiteit;
Open jou siel vir jou maat – geestelike intimiteit en
Deel jou lyf met jou maat – seksuele intimiteit.
Chapman sê intimiteit tussen man en vrou spoel oor na die res van die verhoudings in die gesin. Hy sê in gelukkige gesinne is ’n gesonde huwelik die grootste prioriteit vir lewensmaats. ’n Gesonde huwelik impliseer intimiteit en skep die hoogste vlak van emosionele veiligheid vir kinders.
Ouers wat lei
In ’n gesonde gesin neem ouers verantwoordelikheid om hul kinders te lei – ook deur dissipline. Ouers doen dit op verskillende maniere deur byvoorbeeld te verduidelik waarom sekere reëls geld of om te lei deur ’n voorbeeld te stel. Chapman meen dit is moontlik vir twee ouers wat verskillende benaderings het tot leiding om suksesvolle uitkomste te bereik. Pa is dalk die “kom ons gesels kalm oor die saak”-tipe, terwyl Ma dadelik wil oorgaan tot aksie.
Die bindende faktor is liefde.
Chapman sê geen vorm van leiding of dissipline kan suksesvol wees as ’n kind nie geliefd voel nie. Hy moedig ouers aan om uit te vind watter “liefdestaal” elke kind verstaan en om leiding daarby aan te pas.
Chapman onderskei tussen vyf “liefdestale”:
Woorde van bevestiging:
Prys ’n kind vir goeie gedrag en vertel jou kind hoe lief jy haar het.
Gehaltetyd:
Gee vir jou kind jou onverdeelde aandag deur saam te lees of te speel en na jou kind te luister. Jy kan hoeveel keer vir jou kind sê “Ek is lief vir jou”, maar as dit nie bevestig word deur gehaltetyd nie, sal die kind nie geliefd voel nie.
Fisieke aanraking:
Aanraking is belangrik vir alle kinders, maar sommige kinders floreer deur liefdevolle aanraking soos drukkies. Die soort aanraking verander soos kinders ouer word. Jou tiener wil dalk nie voor al haar vriende ’n drukkie van Ma hê nie, maar wanneer julle alleen is, sal sy dit waardeer.
Geskenke:
Die gee en ontvang van geskenke is volgens Chapman ’n universele uitdrukking van liefde. ’n Geskenk sê vir ’n kind “Ma en Pa het aan my gedink”. Wanneer jy byvoorbeeld op ’n sakereis was en vir jou kind ’n geskenkie terugbring, sê jy eintlik “ek het aan jou gedink terwyl ek weg was”.
Dit hoef nie duur geskenke te wees nie en ’n kind behoort ook nie alles te kry waarvoor sy wens nie. Dit is regtig bloot “die gedagte wat tel”.
Take van dienslewering:
Om dinge vir jou kind te doen wat jou kind sal waardeer, is ’n basiese liefdestaal. Deur maaltye te berei of jou kind te help met huiswerk, verrig jy take van dienslewering.
Chapman sê elke kind het ten minste twee liefdestale waarop hulle reageer. Hy sê om uit te vind wat jou kind se lieftestaal is, moet jy waarneem hoe jou kind haar liefde vir jou uitdruk, oplet na wat jou kind gereeld van jou vra en luister waaroor jou kind die meeste kla.
Gehoorsame kinders
Net soos lande wette nodig het om suksesvol te funksioneer, het gesinne nodig om reëls neer te lê en dit te gehoorsaam. Chapman sê gehoorsaamheid is iets wat geleer moet word, veral omdat kinders gebore word met die eienskap om grense voortdurend te toets. Hy meen in ’n gelukkige gesin sal ouers altyd op twee sake fokus: of die kinders geliefd voel en om seker te maak dat die kinders die gevolge van hul dade ervaar.
Namate kinders ouer word, ontwikkel hulle eer vir hul ouers, sê Chapman. Eer is volgens hom die uitdrukking van respek en dit ontwikkel wanneer kinders die positiewe gedrag van hul ouers begin raaksien en waardeer.
Volgens hom is die grootste eerbewys wat kinders vir hul ouers kan gee die manier waarop hulle in hul eie lewe belê deur ’n goeie leefstyl te kies.
Mans wat liefhê en lei
Chapman sê die idee van Pa as die “leier” in die huis is vir baie moderne vroue verwarrend en omstrede. Hy erken dat baie mans ook dié idee uitbuit deur hul gesinne met ’n ystervuis te beheer.
Maar, sê Chapman, ’n groter gevaar is passiewe, onbetrokke mans wat alle sake rondom die gesin en ernstige besluite as ’t ware aan hul vroue “uitkontrakteer”.
Hy meen daar is iewers tussen die twee uiterstes ’n gesonde plek waar mans verantwoordelik en diep verbind tot hul vroue en kinders is. So ’n man hardloop nie weg as sake moeilik raak nie, maar soek saam met sy gesin na werkbare oplossings.
So ’n man is ’n leier, maar hy lei nie in isolasie nie; hy is ’n dienaar, nie ’n diktator nie.
Hy koester sy vennootskap met sy vrou en wil dáár wees vir haar, maar hy het geen behoefte om haar te oorheers nie.
Wen-gesinne is gesinne wat dien; bestaan uit ’n ma en pa wat ’n premie plaas op intimiteit; ouers het wat lei; kinders het wat hul ouers eer en gehoorsaam en pa’s het wat leiding neem en lief is vir hul gesinne.

First Temple-Era Water Tunnel Revealed in Jerusalem
A tunnel built thousands of years ago – and which may even have been used during King David's conquest of Jerusalem – has been uncovered in the ancient City of David, just outside the Old City and across the street from the Dung Gate.
Renowned Israeli archaeologist Dr. Eilat Mazer, who is leading the dig, revealed the findings from the discovery Thursday morning at an archaeological symposium at the Hebrew University of Jerusalem.
Mazer, who also uncovered King David's palace, has led the world in ancient Jerusalem findings. Some of her other discoveries have included proof of another Biblical story, in the Book of Jeremiah. A completely intact seal impression, or "bula," bearing the name Gedaliahu ben Pashur was uncovered. The bula is actually a stamped engraving made of mortar. Mazer also found a second such impression not far away, as as well as the remnants of a wall from the prophet Nechemia.
The archaeologist said there is a high probability that the tunnel is the one referred to as the "tsinor" in the Biblical story of King David's conquest of Jerusalem (Samuel II, 5:6-8; Chronicles I, 11:4-6).
"The new discoveries in the excavations in the City of David illuminate the ancient history of Jerusalem and the reality described in the Bible," she noted.
Ancient Engineering, Lasting Technology
The opening to the 3,000-year-old tunnel was found earlier this year during the ongoing excavations at the site. The tunnel itself is located under a mammoth stone building that was previously identified as King David's palace, built some time during the 10th century B.C.E., according to the Gregorian calendar.
Barely wide enough to allow a single person through, the walls of the passage were apparently created partly by carving rough stones, partly by making use of the existing bedrock. Only the first 50 meters are accessible at present, since the tunnel is filled with fallen rocks and debris, said Mazer.
Whole, undamaged oil lamps that were characteristic of the First Temple period were found on the floor of the tunnel during the dig.
The archaeologist added that the tunnel was probably used to channel water to a pool by the palace, and eventually was converted to an escape passage near the end of the First Temple period. Additional walls were built to block the tunnel from the sight of anyone of the nearby hill and to protect it from debris filtering in.
The dig, which is being sponsored by the Shalem Center research institute and the City of David Foundation, was carried out under the academic auspices of the Hebrew University.

My Son
It's a Wednesday night and you are at a church prayer meeting when somebody runs in from the parking lot yelling, "Turn on a radio, turn on a radio!" And while the church listens to a little transistor radio with a microphone stuck up to it, the announcement is made: "Two women are lying in a Long Islandhospital dying from a 'mystery' flu." Within hours it seems, this thing just sweeps across the country. People are working around the clock trying to find an antidote. Nothing is working! California, Oregon, Arizona, Florida, Massachusetts.
It's as though it's just sweeping in from the borders. And then, all of a sudden, the news comes out. The code has been broken. A cure can be found A vaccine can be made. It's going to take the blood of somebody who hasn't been infected, and so, sure enough,all through the Midwest, through all those channels of emergency broadcasting, everyone is asked to do one simple thing: Go to your downtown hospital and have your blood type taken. That's all we ask of you. When you hear the sirens go off in your neighborhood, please make your way quickly, quietly, and safely to the hospitals. Sure enough, when you and your family get down there late on that Friday night, there is a long line, and they've got nurses and doctors coming out and pricking fingers and taking blood and putting labels on it.
Your wife and your kids are out there, and they take your blood type and they say, "Wait here in the parking lot and if we call your name, you can be dismissed and go home." You stand around, scared, with your neighbors, wondering what in the world is going on and if this is the end of the world. Suddenly a young man comes running out of the hospital screaming. He's yelling a name and waving a clipboard. What? He yells it again! And your son tugs on your jacket and says, "Daddy, that's me."
Before you know it, they have grabbed your boy. Wait a minute! Hold on! And they say, "It's okay, his blood is clean. His blood is pure. We want to make sure he doesn't have the disease. We think he has got the right type." Five tense minutes later, out come the doctors and nurses, crying and hugging one another some are even laughing. It's the first time you have seen anybody laugh in a week, and an old doctor walks up to you and says, "Thank you, sir. Your son's blood type is perfect. It's clean, it is pure, and we can make the vaccine." As the word begins to spread all across that parking lot full of folks, people are screaming and praying and laughing and crying.
Then the gray-haired doctor pulls you and your wife aside and says, "May we see you for moment? We didn't realize that the donor would be a minor and we need ....... we need you to sign a consent form." You begin to sign and then you see that the number of pints of blood to be taken has been left blank. "H-how many pints?", you ask.
And that is when the old doctor's smile fades and he says, "We had no idea it would be little child. We weren't prepared. I'm sorry sir, we need it all!" "But but .. You don't understand." "We are talking about the world here. Please sign. We need it all!" "But can't you give him a transfusion?" "If we had clean blood we would. Can you sign? Would you sign?"
In numb silence, you do. Then they say, "Would you like to have a moment with him before we begin?" Can you walk back? Can you walk back to that room where he sits on a table saying, "Daddy? Mommy? What's going on?" Can you take his hands and say, "Son, your mommy and I love you, and we would never ever let anything happen to you that didn't just have to be. Do you understand that?" And when that old doctor comes back in and says, "I'm sorry, we've GOT to get started! People all over the world are dying. Can you leave?" Can you walk out while he is saying, "Daddy? Mommy? Daddy? "Why, why have you forsaken me?"
And then next week, when they have the ceremony to honor your son some folks sleep through it .. some folks don't even come because they go to the lake or the seashore .. some folks come with a pretentious smile and just "pretend" to care. Would you want to jump up and say, "MY SON DIED FOR YOU! DON'T YOU CARE?" Is that what GOD wants to say? "MY SON DIED FOR YOU. DON'T YOU KNOW HOW MUCH I CARE?" "FATHER, Seeing it from YOUR eyes breaks our hearts. Maybe now we can begin to comprehend the great Love YOU have for us."

Why is the sky blue? What makes the sunset red?
On a clear sunny day, the sky above us looks bright blue. In the evening, the sunset puts on a brilliant show of reds, pinks and oranges. Why is the sky blue? What makes the sunset red?
To answer these questions, we must learn about light, and the Earth's atmosphere.
THE ATMOSPHERE
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans.
The composition of the atmosphere varies, depending on your location, the weather, and many other things. There may be more water in the air after a rainstorm, or near the ocean. Volcanoes can put large amounts of dust particles high into the atmosphere. Pollution can add different gases or dust and soot.
The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space.
LIGHT WAVES
Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromagnetic spectrum.
Electromagnetic waves travel through space at 299,792 km/sec (186,282 miles/sec). This is called the speed of light.
The energy of the radiation depends on its wavelength and frequency. Wavelength is the distance between the tops (crests) of the waves. Frequency is the number of waves that pass by each second. The longer the wavelength of the light, the lower the frequency, and the less energy it contains.
COLORS OF LIGHT
Visible light is the part of the electromagnetic spectrum that our eyes can see. Light from the sun or a light bulb may look white, but it is actually a combination of many colors. We can see the different colors of the spectrum by splitting the light with a prism. The spectrum is also visible when you see a rainbow in the sky.
The colors blend continuously into one another. At one end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy.
LIGHT IN THE AIR
Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits.
Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors.
Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies (blues) are absorbed more often than the lower frequencies (reds). This process is called Rayleigh scattering. (It is named after Lord John Rayleigh, an English physicist, who first described it in the 1870's.)
WHY IS THE SKY BLUE?
The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.
THE BLACK SKY AND WHITE SUN
On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow.
Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes.
WHY IS THE SUNSET RED?
As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less bright. The color of the sun itself appears to change, first to orange and then to red. This is because even more of the short wavelength blues and greens are now scattered. Only the longer wavelengths are left in the direct beam that reaches your eyes.
The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.
To answer these questions, we must learn about light, and the Earth's atmosphere.
THE ATMOSPHERE
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%). Argon gas and water (in the form of vapor, droplets and ice crystals) are the next most common things. There are also small amounts of other gases, plus many small solid particles, like dust, soot and ashes, pollen, and salt from the oceans.
The composition of the atmosphere varies, depending on your location, the weather, and many other things. There may be more water in the air after a rainstorm, or near the ocean. Volcanoes can put large amounts of dust particles high into the atmosphere. Pollution can add different gases or dust and soot.
The atmosphere is densest (thickest) at the bottom, near the Earth. It gradually thins out as you go higher and higher up. There is no sharp break between the atmosphere and space.
LIGHT WAVES
Light is a kind of energy that radiates, or travels, in waves. Many different kinds of energy travel in waves. For example, sound is a wave of vibrating air. Light is a wave of vibrating electric and magnetic fields. It is one small part of a larger range of vibrating electromagnetic fields. This range is called the electromagnetic spectrum.
Electromagnetic waves travel through space at 299,792 km/sec (186,282 miles/sec). This is called the speed of light.
The energy of the radiation depends on its wavelength and frequency. Wavelength is the distance between the tops (crests) of the waves. Frequency is the number of waves that pass by each second. The longer the wavelength of the light, the lower the frequency, and the less energy it contains.
COLORS OF LIGHT
Visible light is the part of the electromagnetic spectrum that our eyes can see. Light from the sun or a light bulb may look white, but it is actually a combination of many colors. We can see the different colors of the spectrum by splitting the light with a prism. The spectrum is also visible when you see a rainbow in the sky.
The colors blend continuously into one another. At one end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy.
LIGHT IN THE AIR
Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits.
Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors.
Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the colors can be absorbed. But the higher frequencies (blues) are absorbed more often than the lower frequencies (reds). This process is called Rayleigh scattering. (It is named after Lord John Rayleigh, an English physicist, who first described it in the 1870's.)
WHY IS THE SKY BLUE?
The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.
THE BLACK SKY AND WHITE SUN
On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow.
Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes.
