Jesus Christ, might not have been the first one to come to mind when you thought of this; seeing as he did preach some long messages, such as the sermon on the mount, but many of his most powerful messages were limited to only three words. Yes, Jesus had such linguistic power that even Shakespeare would be impressed, and for that reason, we would like to look as some of Jesus' short sermons.
First on the list we go to Jesus' trial with Pilate. The Pharisees have brought Jesus before pilate accusing him of treason toward Cesar. Pilate hearing this accusation simply asks Jesus "Art thou the kings of the Jews?" To which Jesus replied, "Thou sayest it."(Luke 23:3) This statement might not seem like much, but it was uncharacteristic of a guilty man. He doesn't make any excuse, he simply says, thats what they are saying of me. No where in the gospel does Jesus claim to be a king, but here are others claiming that he is. When you have convinced others of who you truly are, a selfish claim is unnecessary. Pilate understanding the wisdom of Christ, and that he quit possibly was who they accused him of said, "I find no fault in this man." (Luke 23:4)
Next we go to the stormy waters of the sea of Galilee. Jesus has told his disciple to enter into a ship and pass over unto the other side of the sea. During their voyage, a storm arises and fills the ship with water; obviously to the point that they may perish. The disciples go to Jesus who was asleep in the ship, and wake him and saying "carest thou not that we perish?" to which Christ raises up and says "peace be still." (Mark 4:38-39) Wow, what a way to hush a bunch of anxiety stricken men. Jesus proved to them that when he is with you there is no need to fear, solutions to your problems are within his lips. Next time you have a problem remember you serve the one who can say "peace be still."
Lastly we will look at a lepor who came to Jesus. The Leper seeing Jesus and knowing of his reputation said to him, "If though wilt, thou canst make me clean." Jesus seeing this mans faith, had compassion and simply said..."be thou clean." and the diagnosis read, "immediately the leprosy departed from him." (Luke 5:13) Not only does Jesus have the power to cleanse you of your sickness, but to those with a guilty conscience trying to find relief, he can say "be thou clean." O, why carry the burden any longer when he can cleanse so easily?
May God bless you
