God Is Light
Darkness can be defined as "an absence of light." Since "God is light, and in Him is no darkness at all." (1 John 1:5 KJV), it's natural that the physical creation (see The Seven Days Of Creation; also How Old Is God?) began with the displacement of darkness: "And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day." (Genesis 1:2-5 KJV)
"But all the children of Israel had light"
Darkness is referred to widely throughout the Old and New Testaments, literally and figuratively, in past events of Bible History, and in coming events of Prophecy:
Some references to literal darkness, all of which represent a separation from God in one form or another:
"And The Lord [see YHVH, Adonai, Jehovah, LORD] said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt. And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days: They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings." (Exodus 10:21-23 KJV) (see also The Ten Plagues)
"If I wait, the grave is mine house: I have made my bed in the darkness. I have said to corruption, Thou art my father: to the worm, Thou art my mother, and my sister. And where is now my hope? as for my hope, who shall see it? They shall go down to the bars of the pit, when our rest together is in the dust." (Job 17:13-16 KJV) (see What Happens When You Die?)
"Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory." (Matthew 24:29-30 KJV) [see also "To Meet The Lord In The Air"]
Some figurative examples of darkness, all of which also represent a separation from God in one form or another:
"The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined." (Isaiah 9:2 KJV)
"And have no fellowship with the unfruitful works of darkness, but rather reprove them. For it is a shame even to speak of those things which are done of them in secret. But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light." (Ephesians 5:11-14 KJV)
"4:18 But the path of the just is as the shining light, that shineth more and more unto the perfect day.
4:19 The way of the wicked is as darkness: they know not at what they stumble." (Proverbs 4:18-19 KJV)
Fact Finder: (a) Did darkness come over the land as Jesus Christ was dying on the cross? (b) Why was even the Messiah in darkess for that time?
