4 Meanwhile the ship which carries the disciples, that is, the Church, is tossed and shaken by the tempests of temptation; and the contrary wind, that is, the devil her adversary, rests not, and strives to hinder her from arriving at rest. But greater is “He who makes intercession for us.” For in this our tossing to and fro in which we toil, He gives us confidence in coming to us, and strengthening us; only let us not in our trouble throw ourselves out of the ship, and cast ourselves into the sea. For though the ship be in trouble, still it is the ship. She alone carries the disciples, and receives Christ. There is danger, it is true, in the sea; but without her there is instant perishing. Keep yourself therefore in the ship, and pray to God. For when all counsels fail, when even the rudder is unserviceable, and the very spreading of the sails is rather dangerous than useful, when all human help and strength is gone, there remains only for the sailors the earnest cry of entreaty, and pouring out of prayer to God. He then who grants to sailors to reach the haven, shall He so forsake His own Church, as not to bring it on to rest?
