VERSE 8. For he that wrought effectually in Peter.
With these words Paul refutes another argument of the false apostles. "What reason have the false apostles to boast that the Gospel of Peter was mighty, that he converted many, that he wrought great miracles, and that his very shadow healed the sick? These reports are true enough. But where did Peter acquire this power? God gave him the power. I have the same power. I received my power, not from Peter, but from the same God, the same Spirit who was mighty in Peter was mighty in me also." Luke corroborates Paul's statement in the words: "And God wrought special miracles by the hands of Paul, so that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them." (Acts 19:11-12.)
To conclude, Paul is not going to be inferior to the rest of the apostles. Some secular writers put Paul's boasting down as carnal pride. But Paul had no personal interest in his boasting. It was with him a matter of faith and doctrine. The controversy was not about the glory of Paul, but the glory of God, the Word of God, the true worship of God, true religion, and the righteousness of faith.
