John 21:18-19 (NIV)
(Jesus speaking) “I tell you the truth, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go.” Jesus said this to indicate the kind of death by which Peter would glorify God. Then he said to him, “Follow me!”
There is “a great difference between spiritual immaturity and maturity. A mark of spiritual maturity is a consciousness of one’s helplessness and need for dependence upon God. There should come a time in our growth when the initiative of our lives passes from us to Him. And this transfer of initiative involves the negation of personal choice consummated in a personal cross. The object of this cross is the glory of God and with it the ultimate object of all guidance.” Only the fully guided life is a truly contented life (Psalm 23:1).
