Commentaries:
If a person truly believes, he will repent, and the consequence is reconciliation with God. Our relationship to Him changes; it is entirely new. Our point of view, our world view, changes. We no longer look at life in the same way. Now we view everything from the perspective of God, His Word, and His Kingdom. We no longer look upon people as we did before.
Before our reconciliation we had a superficial view of Christ. Now we view Him as the Eternal Creator, Lord, Savior, and High Priest who lives in us by His Spirit and with whom we are now in fellowship. This has a tremendous impact on how we conduct our lives.
We understand that God is creating a new race beginning with Christ, the second Adam. A man in Christ is a new creation, not merely improved or reformed, but remade. Reconciliation is not just politely ignoring hostilities. It is the total removal of hostilities so there can be a relationship, a fellowship, between God and man that will produce sanctification leading to holiness and complete and total at-one-ment with the great God.

Separation and At-One-Ment
Paul describes what happened to Abraham at his calling and must happen to us. Abraham's mind—and therefore his life—was so arrested and redirected by God's revelation of Himself that he responded dramatically, despite the realization that he could no longer live as he had for 70 years. He had to make changes, and some of them would be considerable and costly.
He could no longer live completely for himself. He no longer perceived people as he had all his life. He especially could no longer perceive his new God and Savior as He formerly had. A new man was being created from within, so he had to make a clean and permanent break from his old life. His life now had a new Object toward which he must walk. His life had a new direction, a new relationship, new desires, and new requirements to fulfill.
We must never forget that Abraham was a special case; he is the prototype who set a vivid, overall example for all his spiritual children to follow to some degree. There were bumps along the way; at times, he fell short of the ideal. Yet, on the whole, he did nothing less than set a superb example for all of us.

The Christian Fight (Part Six)
Paul uses very strong language here. Not one part of this system will be carried over into the World Tomorrow! The whole thing is unclean, something that contaminates and defiles, rendering unholy those who are touched by it (Haggai 2:10-14). The world is most dangerous to a Christian when it is not persecuting them. It seems friendly, tolerant, even producing good, but God says even then it is still unclean. It is God's judgment that counts.
