Let There Be Light!




GENESIS 1:3-4 reads,

And God said: 'Let there be light.' And there was light.

וַיֹּאמֶר אֱלֹהִים, יְהִי אוֹר; וַיְהִי-אוֹר.

God saw that the light was good, and he separated the light from the darkness.

וַיַּרְא אֱלֹהִים אֶת-הָאוֹר, כִּי-טוֹב; וַיַּבְדֵּל אֱלֹהִים, בֵּין הָאוֹר וּבֵין הַחֹשֶׁךְ.

Why did God create the LIGHT?
Let’s hear from the scientists;
Circadian Rhythm and Light
Biological rhythms that repeat at an approximately 24-hour interval are called “circadian rhythms.” They have been found in plants and animals, as well as humans. Light is the main stimulus that helps “set” the circadian clock, and thus circadian rhythms keep a synchronized rhythm with the solar day. If we are not exposed to sufficient amounts of light for a sufficient amount of time and with the right timing, our biological clocks become desynchronized with the solar day. In humans, decreasing physiological functions and neurobehavioral performance, and sleep problems may occur. Of particular concern is the cyclical level of the “hormone melatonin” in humans. It’s believed that melatonin is vital to regulation of our physiology at night. Light at night reduces melatonin levels. With less melatonin, we may also be more susceptible to illness.

An article from Chicago Tribune, April 2004 reads;
Shanghai, called the "city with no night" because of its extravagant electric signs, is about to dim the lights in an effort to cut light pollution. The chief of lights and advertisements for the city's environmental bureau said the lights make it hard for residents to sleep, wash out the night sky and hurt the environment.

Why do Day and Night exist?

In heaven there is perfect light, and no darkness at all; in hell, only darkness, and no gleam of light. The day and the night are the Lord's; let us use both to his honor, by working for him every day, and resting in him every night, meditating in his Word both day and night.

Lord Jesus, let us live for you day and night and through eternity! Amen.
