What is the proof that carnality has gone?

When carnality (Note 1) is gone you will know it. It is the most real thing you can imagine. And God will see to it that you have a number of opportunities to prove to yourself the miracle of His grace. The proof is in a very practical test. You will find yourself saying, “If this had happened before, I would have had the spirit of resentment!” And you will never cease to be the most amazed person on earth at what God has done for you on the inside.

Note 1: Biblical carnality: metaphorically our propensity to sin, to chase after things of the flesh and of the World, rather than of the Spirit.
