John 21:18
'Very truly, I tell you, when you were younger, you used to fasten your own belt and go wherever you wished; but when you are old, you will stretch out your hands, and someone else will fasten a belt around you and take you where you do not wish to go' — this prophecy presages Peter's martyrdom by crucifixion (later tradition: crucified upside down). The contrast between youthful autonomy ('go wherever you wished') and aged dependence (being led where he 'does not wish') indicates surrender to divine will through suffering. The 'stretching out of hands' imagery suggests cruciform death, the ultimate following of Jesus.
