1) God creates humans on the sixth day of creation, marking the climax of his creation plan. 2) When God says "Let us make man in our image", he is referring to himself and the Trinity, showing they are all engaged in the creation process. 3) God's ultimate purpose in creation is to have a redeemed humanity who will serve as a bride for his Son and populate heaven in eternal praise and worship. The creation of the universe and earth was merely a stage to allow this plan to unfold.
