MATTHEW 14 22 Immediately Jesus made His disciples get into the boat and go before Him to the other side, while He sent the multitudes away. 23 And when He had sent the multitudes away, He went up on the mountain by Himself to pray. Now when evening came, He was alone there. 24 But the boat was now in the middle of the sea, tossed by the waves, for the wind was contrary.25 Now in the fourth watch of the night Jesus went to them, walking on the sea. 26 And when the disciples saw Him walking on the sea, they were troubled, saying, “It is a ghost!” And they cried out for fear.27 But immediately Jesus spoke to them, saying, “Be of good cheer! It is I; do not be afraid.”28 And Peter answered Him and said, “Lord, if it is You, command me to come to You on the water.”29 So He said, “Come.” And when Peter had come down out of the boat, he walked on the water to go to Jesus. 30 But when he saw that the wind was boisterous, he was afraid; and beginning to sink he cried out, saying, “Lord, save me!”31 And immediately Jesus stretched out His hand and caught him, and said to him, “O you of little faith, why did you doubt?” 32 And when they got into the boat, the wind ceased.33 Then those who were in the boat came and worshiped Him, saying, “Truly You are the Son of God.”34 When they had crossed over, they came to the land of Gennesaret. 35 And when the men of that place recognized Him, they sent out into all that surrounding region, brought to Him all who were sick, 36 and begged Him that they might only touch the hem of His garment. And as many as touched it were made perfectly well.

Meanwhile the boat carrying the disciples—that is, the church—is rocking and shaking amid the storms of temptation, while the adverse wind rages on. That is to say, its enemy the devil strives to keep the wind from calming down. But greater is he who is persistent on our behalf, for amid the vicissitudes of our life he gives us confidence. He comes to us and strengthens us, so we are not jostled in the boat and tossed overboard. For although the boat is thrown into disorder, it is still a boat. It alone carries the disciples and receives Christ. It is in danger indeed on the water, but there would be certain death without it. Therefore stay inside the boat and call upon God. When all good advice fails and the rudder is useless and the spread of the sails presents more of a danger than an advantage, when all human help and strength have been abandoned, the only recourse left for the sailors is to cry out to God. Therefore will he who helps those who are sailing to reach port safely, abandon his church and prevent it from arriving in peace and tranquility?
