The Christian must first understand that God is eternal and dwells in the dimension of eternity. He has no beginning; He has no end. There is no past or future with God. He dwells in the infinite present tense of His continual existence.
In the light of this truth concerning God, all His purposes and plans are found in eternity. God created the universe, including the angels, in dateless time (Gen. 1:1). Our concept of time did not come into existence until Genesis 1:3. When God created the dimension of time, He automatically declared the concept of beginnings—establishing a past, a present, and a future.
