Note 5 at Gal. 6:14: Notice that Paul's critics gloried in the carnal things they accomplished while Paul gloried only in what Jesus had done for him through the cross. One way to discern a true man or woman of God is to see where their boasting lies. Those who boast in their own accomplishments are suspect, while those who boast in the Lord are the true and faithful witnesses.

Note 6 at Gal. 6:14: Notice that there is a double crucifixion. The world was crucified unto Paul and Paul was crucified unto it. This means that the world's system had nothing to offer Paul and Paul had nothing to offer the world outside of Christ. It's one thing to remove yourself from the world's system, but it's another thing to remove the world's system from you. Paul had done both. Paul's sole purpose in life was to bring glory unto the risen Christ.
