Another revelation of our Lord's relation to His disciples is given in the fact that He changes Simon's name. Jehovah, in the Old Testament, changes the names of Abraham and of Jacob. Babylonian kings in the Old Testament change the names of their vassal princes. Masters impose names on their slaves; and I suppose that even the marriage custom of the wife's assuming the name of the husband rests originally upon the same idea of absolute authority. That idea is conveyed in the fact that our Lord changes Peter's name, and so takes absolute possession of him, and asserts His mastery over him. We belong to Him altogether, because He has given Himself altogether for us. His absolute authority is the correlative of His utter self-surrender. He who can come to me and say, 'I have spared not my life for thee,' and He only, has the right to come to me and say, 'yield yourself wholly to Me.' So, Christian friends, your Master wants all your service; do you give yourselves up to Him out and out, not by half and half.
Lastly, that change of name implies Christ's power and promise to bestow a new character and new functions and honours. Peter was by no means a 'Peter' then. The name no doubt mainly implies official function, but that official function was prepared for by personal character; and in so far as the name refers to character, it means firmness. At that epoch Peter was rash, impulsive, headstrong, self-confident, vain, and therefore, necessarily changeable. Like the granite, all fluid and hot, and fluid because it was hot, he needed to cool in order to solidify into rock. And not until his self-confidence had been knocked out of him, and he had learned humility by falling; not until he had been beaten from all his presumption, and tamed down, and sobered and steadied by years of difficulty and responsibilities, did he become the rock that Christ meant him to be. All _that_ lay concealed in the future, but in the change of his name, while he stood on the very threshold of his Christian career, there was preached to him, and there is preached to us, this great truth, that if you will go to Jesus Christ He will make a new man of you. No man's character is so obstinately rooted in evil but that Christ can change its set and direction. No man's natural dispositions are so faulty and low but that Christ can develop counterbalancing virtues, and out of the evil and weakness make strength. He will not make a Peter into a John, or a John into a Paul, but He will deliver Peter from the 'defects of his qualities,' and lead them up into a higher and a nobler region. There are no outcasts in the view of the transforming Christ. He dismisses no people out of His hospital as incurable, because anybody, everybody, the blackest, the most rooted in evil, those who have longest indulged in any given form of transgression, may all come to Him; with the certainty that if they will cleave to Him, He will read all their character and all its weaknesses, and then with a glad smile of welcome and assured confidence on His face, will ensure to them a new nature and new dignities. 'Thou art Simon—thou shalt be Peter.'
The process will be long. It will be painful. There will be a great deal pared off. The sculptor makes the marble image by chipping away the superfluous marble. Ah! and when you have to chip away superfluous flesh and blood it is bitter work, and the chisel is often deeply dyed in gore, and the mallet seems to be very cruel. Simon did not know all that had to be done to make a Peter of him. We have to thank God's providence that we do not know all the sorrows and trials of the process of making us what He wills us to be. But we may be sure of this, that if only we keep near our Master, and let Him have His way with us, and work His will upon us, and if only we will not wince from the blows of the Great Artist's chisel, then out of the roughest block He will carve the fairest statue; and He will fulfil for us at last His great promise: 'I will give unto him a white stone, and in the stone a new name written, which no man knoweth save he that receiveth it.'
