Genesis 1:26 (ESV)

26 Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.”

God speaks for the second time on the sixth day. The entire natural world with its plants and animals has been created. The glory of it was much greater compared to what we see of it today. Not a single species of animal or plant was extinct at that time.

Yet, according to God’s plan, one creature was still missing: the creature that was made in his image. The Lord uses a striking phrase in the creation of man: “Let us make man [adam; mankind] in our image, after our likeness” (emphasis added). God is one and yet he speaks of us and our. These words already show in the first chapter of the Bible that God consists of persons. The plural us is reality in God. Other examples in the Old Testament of this are Genesis 3:22; Genesis 11:7; Isaiah 6:8.
