1 Timothy 1 (The Message)
12-14 I'm so grateful to Christ Jesus for making me adequate to do this work. He went out on a limb, you know, in trusting me with this ministry. The only credentials I brought to it were invective and witch hunts and arrogance. But I was treated mercifully because I didn't know what I was doing—didn't know Who I was doing it against! Grace mixed with faith and love poured over me and into me. And all because of Jesus.
Paul's ministry had nothing to do with his credentials but because of Jesus. The grace of God empowers Paul in his ministry - this is new covenant ministry.
