The 'us' reveals the Trinity — Father, Son, and Holy Spirit together in the act of creation. Humanity is made uniquely in God's image, set apart from all other creatures, and given the responsibility of stewardship over the earth.
Memory phrase: God made people to be like Him.
Talk about it: God said 'let us' — that means more than one! Do you know who was there with God?
Prayer: God — Father, Son, and Holy Spirit — thank You for deciding together to make me. I am not an accident.
