From John Piper’s recent sermon, I Act the Miracle:
. . . The ground for my trembing here is not threat, but gift. Tremble! God Almighty, the Creator of the universe, your Father, your Redeemer, your Sustainer is in you willing and working. Tremble! Your acting is his acting. That’s what I meant by “I don’t wait for a miracle, I act the miracle.”
My attack on my sin in reliance upon the Holy Spirit rooted in the gospel is God’s act, not mine.
“Work out your own salvation with fear and trembling, for it is God who works in you both to will and to work for his good pleasure”—Phil. 2:12-13
