The Apostle Peter knew what it was to betray Jesus. He denied the Lord three times in an attempt to save himself from the agony of the cross. But after Jesus died and rose, Peter was filled an other-wordly courage. For he saw not only that Jesus is the Christ, but also that he is the sort of Christ who rules all things. He saw that he is Lord even over the grave. And what fear can remain in service to a Lord such as this? What resistance would keep us from following him? Only the blind folly of calling ourselves lords and seeking our own salvation as if we were Christ.
