Matthew 14:25-31 [NLT] About three o'clock in the morning Jesus came toward them, walking on the water. 26 When the disciples saw Him walking on the water, they were terrified. In their fear, they cried out, "It's a ghost!" 27 But Jesus spoke to them at once. "Don't be afraid," He said. "Take courage. I am here! " 28 Then Peter called to Him, "Lord, if it's really You, tell me to come to You, walking on the water." 29 "Yes, come," Jesus said. So Peter went over the side of the boat and walked on the water toward Jesus. 30 But when he saw the strong wind and the waves, he was terrified and began to sink. "Save me, Lord!" he shouted. 31 Jesus immediately reached out and grabbed him. "You have so little faith," Jesus said. "Why did you doubt Me?"
Peter ventured out of the boat to be with Christ and was initially very successful. It took much courage to leave the safety of the ship to walk on the tempestuous water in the dark. Soon, however, he realized he could not continue on his own and began to sink. When he cried for help, the Lord immediately sustained him and brought him to safety. So it is with us when we began to sink into our sea of troubles, if we cry to the Lord, he will hold us up and bring us to a place of calm and safety.
