We were made in the image of God – Gen 1:26.
We know that Jesus is the image of the invisible God – Col 1:15.
As Christians we get the image of God in us restored – Col 3:10, Eph 4:24 and 2 Cor 3:12-18
I do not believe that sin removes the image of God from within humanity. I do believe sin mars the image of God within us…making it harder to see and harder for his image in us to do any sort of convicting work in the world. Our reconciliation to God, through Christ, by the Spirit works to renew and restore God’s image in us. It doesn’t put it back in as if it was gone. It renews it and makes it more obvious to spot. When the world sees us, they need to get a clearer idea of what God is like.
