In the fourteenth chapter of Matthew, the disciples were in a ship out on the sea being tossed with waves for the wind was Contrary.  In the fourth watch of the night, Jesus went unto them walking on the sea, and when the disciples saw him walking on the sea, they were troubled, and they cried out for fear, saying it is a spirit.  But straightway, Jesus spoke unto them saying be of good cheer.  It is I.  Be not afraid.  Peter answer and said unto him, Lord, if it be thou, bid me to come to thee on the water, and Jesus said come.   Now, when Peter was come down out of the ship, he walked on the water to go to Jesus, but when he saw the wind boisterous, he was afraid, and he began to sink, and he cried out, Lord, save me.  Peter was doing alright while he kept his eyes on Jesus, but when he looked away at the waves rolling about him, he began to sink.  And straightway, Jesus stretched forth his hand and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?  Being tossed about in this life by disappointments and temptations, we are very much like Peter.  If we want to live for Jesus, we must keep our eyes on him, and not on the things of this world.
