"Let me put this question to you: How did your new life begin? Was it by working your heads off to please God? Or was it by responding to God's Message to you? Are you going to continue this craziness? For only crazy people would think they could complete by their own efforts what was begun by God. If you weren't smart enough or strong enough to begin it, how do you suppose you could perfect it? Did you go through this whole painful learning process for nothing? It is not yet a total loss, but it certainly will be if you keep this up!
Answer this question: Does the God who lavishly provides you with his own presence, his Holy Spirit, working things in your lives you could never do for yourselves, does he do these things because of your strenuous moral striving or because you trust him to do them in you?"
