"Seeing ye have purified your souls in your obedience to the truth unto unfeigned love of the brethren, love one another from the heart fervently: having been begotten again, not of corruptible seed, but of incorruptible, through the word of God, which liveth and abideth. For all flesh is as grass, and all the glory thereof as the flower of grass. The grass withereth, and the flower falleth: but the word of the Lord abideth for ever. And this is the word of good tidings which was preached unto you. Putting away therefore all wickedness, and all guile, and hypocrisies, and envies, and all evil speakings, as new-born babes long for the spiritual milk which is without guile, that ye may grow thereby unto salvation; if ye have tasted that the Lord is gracious."--1 PETER i. 22-ii. 3.
That holy lives have been lived in solitude none would venture to dispute, and that devout Christians have found strength for themselves and given examples to the world by withdrawal from the society of their fellows is attested more than once in the history of Christendom. But with lives of such isolation and seclusion the New Testament exhibits little sympathy. To whatever preparation the Christian is exhorted, it is never with a view to himself. Though not of the world, he is to be in the world, that men may profit by his example. The prayer of the Lord for His disciples ere He left them was, not that they might be taken out of the world, but protected from its evils.
Christ's intention was to found a Church, a communion, a brotherhood, and all His language looks that way: "One is your Master, and all ye are brethren"; "So let your light shine before men that they may see your good works and glorify your Father which is in heaven." And of like character is the teaching of the Epistles: "Be kindly affectioned in love of the brethren" (Rom. xii. 10); "Let brotherly love continue" (Heb. xiii. 1). We are in no way surprised therefore when St. Peter turns from his exhortations to personal sobriety, obedience, and holiness, and addresses the converts on the application of these virtues, that through them they may bind in closer bonds the brotherhood of Christ: _Seeing ye have purified your souls in your obedience to the truth unto unfeigned love of the brethren, love one another from the heart fervently_. Obedience is the sole evidence by which the believer can show that God's call has wrought in him effectually. His election is of the Father's foreknowledge, his sanctification is the gift of the Holy Spirit, and it is the sprinkling of the blood of Christ which makes him fit for entry into the house of the Father. In the Christian, so called and so aided, there must be a surrender of himself to the guidance of that Spirit which deigns to guide him. The law in his members must be mortified, and another and purer law accepted as the rule of his life. This law St. Peter calls "the truth" because it has been made manifest in its perfection in the life of Jesus, who is the Way, the Truth, and the Life. Of this example St. Paul testifies as "the truth which is in Jesus." He therefore who would cherish the Christian hope will purify himself even as Christ is pure. The way and means unto such purification is obedience.
This first and most needful step the Apostle believes, from his knowledge of their lives, that these Asian converts have taken in earnest, and thus have attained to a love of their brethren which differs utterly from the love which the world exhibits, which is true, sincere, unfeigned. But the believer's life is a life of constant progress. Daily advance is the evidence of vitality. All the language which Scripture applies to it proclaims this to be its character. It is called a walk, a race, a pilgrimage, a warfare. The Christian all his life through will find himself so far from what Christ intends to make him that he must ever be pressing forward. Hence, though they have attained to a stage of purification, have put off in some degree the old man, the Apostle's exhortation is, "Press forward"; "Love one another from the heart fervently." The English word describes a warmth and earnestness of love which is deep-seated and true, but the original expresses more than this, more of the sustained effort to which St. Peter is urging them. It points to incessant striving, to a constancy like that of the prayers of the Church for the Apostle himself when he was in prison, a prayer made unto God without ceasing. So steadfast must be the Christian love; and such love the purified, undistracted heart alone can manifest, a heart which has been released from the entanglements of earthly ambitions and strivings, whose affections are fully set on the things above.
