In comparison with the precious "blood of Christ" Peter characterizes silver and gold, which men call precious metals, as "corruptible things," and then gives the striking exhortation, "Seeing ye have purified your souls in obeying the truth through the Spirit unto unfeigned love of the brethren, see that ye love one another with a pure heart fervently," and all this on the basis of the new birth which they had already received "of the incorruptible seed by the word of God." Why, Peter, although a fisherman and an unlearned and ignorant man, yet when thou writest under the inspiration of the Holy Ghost, it is almost as hard to keep up with thee as with thy beloved brother, Paul! See how holiness is, as it were, piled up and repeated in various ways in the sentence quoted above. (1), "Ye have purified your souls." Yes, and it was Peter who spoke before the council at Jerusalem in reference to Cornelius and his household, and said that God "put no difference between us and them, purifying their hearts by faith." The word "purify" is derived from a Greek root which means "fire." Souls are purified by the fire of the Holy Spirit, and the result is a continual "obeying the truth," and (2), the positive side of this purification is "unfeigned love of the brethren," and this is love with a pure heart and fervent, the same love which John calls perfect love, and the standard of which is in the words of the Lord Jesus, "As I have loved you that ye also love one another." Was ever more holiness crowded into a single verse? Peter had never been to a Theological Seminary, but he had listened through three eventful years to the blessed teachings of the Lord Jesus, and he had been filled with the Holy Ghost on the day of Pentecost, and without aiming at system or explanation, he has compressed more sound theology into a single verse than we find in many a voluminous treatise and many a lengthy commentary and many an eloquent sermon. And then in the rapturous eloquence of inspiration he tells us how to grow in grace. "Wherefore, laying aside all malice and all guile, and hypocrisies, and envies, and all evil speakings, as newborn babes desire the sincere milk of the word, that ye may grow thereby," and his last exhortation at the end of the second epistle is, "But grow in grace and in the knowledge of our Lord and Saviour, Jesus Christ."
