Matthew 14:22-36
   But Jesus immediately said to them:  “Take
courage!  It is I.  Don’t be afraid.”
   “Lord, if it’s you,”  Peter replied, “tell me to come
to you on the water.”
   “Come,” he said.
   Then Peter got down out of the boat, walked on
the water and came toward Jesus.  But when he
saw the wind, he was afraid and, beginning to
sink, cried out, “Lord, save me!”
