Three years before, Jesus had said - "Fol ow Me," and Peter had fol owed easily, the fascination of Jesus was upon him, he did not need the Holy Spirit to help him to do it. Then he came to the place where he denied Jesus, and his heart broke. Then he received the Holy Spirit, and now Jesus says again - "Fol ow Me." There is no figure in front now saving the Lord Jesus Christ. The first "Fol ow Me" had nothing mystical in it, it was an external fol owing; now it is a fol owing in internal martyrdom (cf. John 21:18).
