The day is thine, the night also is thine: thou hast prepared the light and the sun (Psalm 74:16).
One of the traditional discrepancies attributed by the skeptics to the Genesis account of creation is the fact that there was light (Hebrew or) on the first day of creation week, whereas God did not create the lights (Hebrew ma-or) to rule the day and the night until the fourth day.
However, it is interesting that modern evolutionary cosmologists find no problem in having light before the sun. According to their speculative reconstruction of cosmic history, light energy was produced in the imaginary Big Bang 15 billion years ago, whereas the sun evolved only five billion years ago. Thus, even in their attempts to destroy the divine revelation of Genesis, they inadvertently find it necessary to return to its concepts. Light energy somehow had to be prepared before the sun and other stars could ever be set up to serve as future generators of light energy. The fact that light is an entity independent of the sun and other heavenly bodies is one of the remarkable scientific insights of the Bible. As the basic form of energy (even intrinsic in the very nature of matter, as expressed in the famous Einstein equation), it is significant that the first recorded word spoken by the Creator was: Let there be light (Genesis 1:3).
In this chapter, the psalmist is entreating the Lord of light, the Creator of all things, to deliver His people from those who are seeking to destroy all genuine faith in the true God of heaven. The tumult of those that rise up against thee increaseth continually (v.23). Nevertheless, God is my King of old, working salvation in the midst of the earth (v.12). The mighty God of creation, who established and controls all the basic energies of the cosmos and their manifestation on the earth, is fully able to defeat His enemies and establish His people. We can be sure of that. HMM
