Adam was our chief representative. When he fell into the bondage of sin, so did all of the human race. In this state, we began to turn away from God. We started worshiping false gods, and we suppressed the truth about the one true God, until we had lost our apprehension of Him. Romans 1:21 says: “For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking and their foolish hearts were darkened.”
The only way that we can be brought to the light, is by the almighty hand of God, who regenerates us and frees us from the bondage that sin had upon us (2 Cor. 1:21-22). Since man was evil, God had to renew His image in man. Through the Incarnation and death of Jesus Christ, we were cleansed from our sin and made new!
We are now commanded to incarnate our faith, just like Jesus incarnated his body. We are to be a city set on a hill & a light for all nations. Our faith should reflect upon who we are. When people see us, they shouldn't just see us, but they should see Christ shining through us. In everything that we do, it should always bring glory to God!
