2 The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters. 3 Then God said, “Let there be light”; and there was light. 4 And God saw the light, that it was good; and God divided the light from the darkness. 5 God called the light Day, and the darkness He called Night. So the evening and the morning were the first day.
It is interesting to note that the first thing God created right after creating time, space, and the earth was something to keep track of what day it was. He could have created everything in the same instant, but He chose to do it in seven days and to help us keep track of the time He just created, He create light so that there will be light and darkness or day and night. “So the evening and the morning were the first day.” Right away, this light and darkness was used to denote one literal, 24 hour day.
Day and night was created to help us keep track of time and to know the days and the seasons. Every person knows what a day means, they live it every day of their lives, so “the evening and the morning” image be used as a reference when we are reading Genesis 1 to know that it means a literal day. All the references to night and day passing shows us that “the first day,” “the second day,” and so on really is just that, one day. There should be no reason why we would interpret these days to be day ages or eras except to incorporate humanistic and evolutionary ideas into the Creation.
If you believe the inerrancy of the Word, why would you try to change the meaning of the words in it to fit your world view?
Jesus is Light
