Peter's imprisonment in Rome

In the providence of God, Peter was permitted to close his ministry in Rome, where his imprisonment was ordered by the emperor Nero about the time of Paul's final arrest. Thus the two veteran apostles, who for many years had been widely separated in their labors, were to bear their last witness for Christ in the world's metropolis, and upon its soil to shed their blood as the seed of a vast harvest of saints and martyrs.PCP 61.3

Since his reinstatement after his denial of Christ, Peter had unflinchingly braved danger and had shown a noble courage in preaching a crucified, risen, and ascended Saviour. As he lay in his cell he called to mind the words that Christ had spoken to him: “Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.” John 21:18. Thus Jesus had made known to the disciple the very manner of his death, and even foretold the stretching of his hands upon the cross.PCP 61.4
