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.'
