John 21:19

This spake He, signifying by what death he should glorify God. And when He had spoken this, He saith unto Him, Follow Me.

The interview with Peter affected also the Lord very deeply, because His love for His disciples was most cordial. Referring probably to the action of Peter in girding his coat about him when the Lord stood on the beach, Jesus tells him that these conditions are still obtaining. He still has his freedom to come and go as he wished. But the time is coming, in his old age, when Peter will be obliged to extend his hands, to be bound and manacled and to be led where he has no natural inclination to go. It was a prophecy of Peter's martyrdom. According to tradition which seems correct, Peter was put to death under the emperor Nero, by crucifixion, thus giving glory and honor and praise to God, even in his death. Only he must follow Christ, his Lord and Savior, at all times, whithersoever he was led. Note: The steadfast believer, sealing his faith with his life, gives glory to, and causes glory to come upon, the name of God and Jesus. Suffering for the sake of Christ belongs to the experiences of the average Christian, and especially of the servants of the Word.
