John 21 includes an intense private conversation between the Lord and Peter that the apostle John was allowed to overhear. Even though Peter was still very tender from his devastating failure during the events leading up to the crucifixion, when he denied knowing Christ, Jesus welcomed him back.
But it was a welcome accompanied by truth. Jesus had work for him to do. He refused to sugarcoat the reality of the life to which Peter had returned. Jesus basically let him know, “This is going to be hard, Peter. If you’re going to follow Me, the way won’t be easy. Feeding My sheep is going to take everything you’ve got.”
When Jesus said, “Where you do not want to go,” we know what He meant because of John’s side note: “(This he said to show by what kind of death he was to glorify God.)” Jesus could see what Peter would face in the future and He knew His disciple would endure.
Church history records that in about AD 65 Peter was executed in Rome under orders from Nero. By the end of his life Peter had been on the road for several decades proclaiming the gospel. He had penned a couple of New Testament letters and probably been Mark’s main source for the second gospel. Peter had a great life of serving God, but he had a tough finish.
Following Christ is not easy. Our Lord never hid that fact. But following Him is best. We’re not sugarcoating anything here. The Christian life is not always smooth going, but it is exactly what we were designed to do and be. It’s the real life. It’s the best life you can possibly have: giving your life to Jesus Christ, living for Him, obeying His Word, having fellowship with His people, and serving in His kingdom.
You don’t know what lies ahead for you. Jesus does. He won’t tell you beforehand, except to assure you that whatever happens, He will be with you every step of the way. He has made that promise (Matthew 28:20) and He will keep it.
