But when he saw the wind, he was afraid, and beginning to sink he cried out, “Lord, save me.” Jesus immediately reached out his hand and took hold of him, saying to him, “O you of little faith, why did you doubt?” Matthew 14:30-31
Hampton Keathley IV , Th.M. writes this about Peter in the water:
(1) His condition
He looks at the circumstances. Peter’s story is the story of all of us. We usually begin good. But in the middle of the situation, we get our eyes off Jesus. We begin to look at our situation and we have no faith.
(2) His cry
The only thing one bound for destruction can cry. “Lord, Save me!”
(3) His conviction
Jesus says Peter’s problem is his lack of faith, his doubt. When the circumstances appear overwhelming, it is the result of doubt. If we are trusting God, then nothing will seem overwhelming, because nothing is overwhelming to God. When my kids have a problem, break something or get their shoestrings in a knot, it is overwhelming to them and they come to me and ask “would you fix this…” They assume that I can do anything. They are still young. But they have the attitude that we should all have towards God.
