Matthew 14:28-31

Peter replied to Him, “Lord, if it is [really] You, command me to come to You on the water.” He said, “Come!” So Peter got out of the boat, and walked on the water and came toward Jesus. But when he saw [the effects of] the wind, he was frightened, and he began to sink, and he cried out, “Lord, save me!” Immediately Jesus extended His hand and caught him, saying to him, “O you of little faith, why did you doubt?”
