“Then, Lord,” Simon Peter replied, “not just my feet but my hands and my head as well!”
Peter does nothing halfway, and when he is convinced by the words of Christ, he dives in headfirst, but his answer is “still the product of self-will. Peter is reluctant to let Jesus do what He wants. He prefers to dictate the terms.” (Morris) “A moment ago he told his Master He was doing too much: now he tells Him He is doing too little” (Dods).
