God made man in His image to defeat Satan.Tony Evans - “God created man to demonstrate what God could do with less when that less is committed to Him, verses what happens to more when that more is in rebellion against Him...God gave mankind the ability to rule to demonstrate to the devil that He could do more through a lesser creature in manifesting His glory than the once-shining star (Satan).”Three things God calls us and equips us to do: 1) Represent His image and nature. Vs 26a - “Then God said, ‘Let us make man in our image, after our likeness…” When people interact with us they are interacting with God Himself. When an athlete puts on a jersey, he represents that team. 2) Rule on His behalf. Vs 26b - “…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…” God gave us power and authority to be like Him on the earth.Authority and responsibility are linked.  3) Reproduce His presence throughout the earth. Vs 28 - “And God blessed them. And God said to them, ‘Be fruitful and multiply and fill the earth and subdue it…” God all living things the ability to co-create with Him. Plants have seed that reproduce plants. Animals and humans have the same ability. Humans are to reproduce more than just physically, but spiritually. Jesus in Matthew 28 - “Go and make disciples.”
