What we produce on our own is filthy rags. We produce our own work, our own effort. What you and I reproduce if we try is our flesh. And there's no life in the flesh...
The flesh profits nothing. The flesh produces nothing. For someone to stand in the pulpit Sunday after Sunday and tell you what you ought to do is a curse on you, because you can't produce it. Have you tried? I did, until the Holy Spirit showed me this: you are dead as a point of origin. Christ in you is the point of origin. He will live the life in you as you.— The Rest of the Gospel: When the partial Gospel has worn you out, pages 84-85
I really like his refrain, "He will live the life in you as you." That is a very nice way of saying it; it sums up Galatians 2:20 very well.
