The Bible says that Jesus has reconciled us in His body of flesh by His death. What does that mean? It can only mean that his dead body was the means by which you were reconciled to God.
Reconciled for what? You were alienated and hostile in your minds, doing evil deeds. Of course, he was talking to Gentiles who had previously been idolaters. But this alienation from God and hostility towards God is not limited to pagan idolaters.
We, too, have this war of the flesh in us, alienation, hostility, evil deeds. This is part of our fallen nature. That is why Jesus had to lay down His life to satisfy the wrath of God toward us and our sins; the perfect for the imperfect, the righteous for the unrighteous, the holy for the unholy.
Our reconciliation with God is a cause of great joy and all that we can do is look to our Father in Christ Jesus and say thank you, Lord.
