Genesis 1:3-5 (New American Standard Bible)

3 Then God said, “Let there be light”; and there was light. 4 God saw that the light was good; and God separated the light from the darkness. 5  God called the light day, and the darkness He called night. And there was evening and there was morning, one day.

    Genesis 1:3 : Ps 33:6, 9; 2 Cor 4:6
    Genesis 1:4 : Ps 145:9, 10
    Genesis 1:4 : Is 45:7
    Genesis 1:5 : Ps 74:16
    Genesis 1:5 : Ps 65:8

The first day and the first night. The first separation of dark and light. The first Day and the plan start to work to set up a biosphere with a way to grow. A way to survive what is to come. Because if we remember nothing else, we must remember that all things happen because God allows it to.  Here is our beginnings our start, our salvation.

I already spoke of verse three but felt the need to include it in the Day 1 of creation.

Day one of month one of the first year of a plan that will bring us all to our Revelation.
