The Old Man vs. The New Man

In Romans 6:6, Paul says, "Knowing this, that our old man was crucified with Him, that the body of sin might be done away with, that we should no longer be slaves of sin."

There are many places in the New Testament where this idea of the old man and the new man are illustrated. In each of these we see godly instruction given, so that all Christians will know who they ought to be in Christ.
