2:1-10 Evil-speaking is a sign of malice and guile in the heart; and hinders our profiting by the word of God. A new life needs suitable food. Infants desire milk, and make the best endeavours for it which they are able to do; such must be a Christian's desires after the word of God. Our Lord Jesus Christ is very merciful to us miserable sinners; and he has a fulness of grace. But even the best of God's servants, in this life, have only a taste of the consolations of God. Christ is called a Stone, to teach his servants that he is their protection and security, the foundation on which they are built. He is precious in the excellence of his nature, the dignity of his office, and the glory of his services. All true believers are a holy priesthood; sacred to God, serviceable to others, endowed with heavenly gifts and graces. But the most spiritual sacrifices of the best in prayer and praise are not acceptable, except through Jesus Christ. Christ is the chief Corner-stone, that unites the whole number of believers into one everlasting temple, and bears the weight of the whole fabric. Elected, or chosen, for a foundation that is everlasting. Precious beyond compare, by all that can give worth. To be built on Christ means, to believe in him; but in this many deceive themselves, they consider not what it is, nor the necessity of it, to partake of the salvation he has wrought. Though the frame of the world were falling to pieces, that man who is built on this foundation may hear it without fear. He shall not be confounded. The believing soul makes haste to Christ, but it never finds cause to hasten from him. All true Christians are a chosen generation; they make one family, a people distinct from the world: of another spirit, principle, and practice; which they could never be, if they were not chosen in Christ to be such, and sanctified by his Spirit. Their first state is a state of gross darkness, but they are called out of darkness into a state of joy, pleasure, and prosperity; that they should show forth the praises of the Lord by their profession of his truth, and their good conduct. How vast their obligations to Him who has made them his people, and has shown mercy to them! To be without this mercy is a woful state, though a man have all worldly enjoyments. And there is nothing that so kindly works repentance, as right thoughts of the mercy and love of God. Let us not dare to abuse and affront the free grace of God, if we mean to be saved by it; but let all who would be found among those who obtain mercy, walk as his people.
2. new-born babes—altogether without "guile" (1Pe 2:1). As long as we are here we are "babes," in a specially tender relation to God (Isa 40:11). The childlike spirit is indispensable if we would enter heaven. "Milk" is here not elementary truths in contradistinction to more advanced Christian truths, as in 1Co 3:2; Heb 5:12, 13; but in contrast to "guile, hypocrisies," &c. (1Pe 2:1); the simplicity of Christian doctrine in general to the childlike spirit. The same "word of grace" which is the instrument in regeneration, is the instrument also of building up. "The mother of the child is also its natural nurse" [Steiger]. The babe, instead of chemically analyzing, instinctively desires and feeds on the milk; so our part is not self-sufficient rationalizing and questioning, but simply receiving the truth in the love of it (Mt 11:25).
desire—Greek, "have a yearning desire for," or "longing after," a natural impulse to the regenerate, "for as no one needs to teach new-born babes what food to take, knowing instinctively that a table is provided for them in their mother's breast," so the believer of himself thirsts after the word of God (Ps 119:1-176). Compare Tatius' language as to Achilles.
sincere—Greek, "guileless." Compare 1Pe 2:1, "laying aside guile." Irenæus says of heretics. They mix chalk with the milk. The article, "the," implies that besides the well-known pure milk, the Gospel, there is no other pure, unadulterated doctrine; it alone can make us guileless (1Pe 2:1).
of the word—Not as Alford, "spiritual," nor "reasonable," as English Version in Ro 12:1. The Greek "logos" in Scripture is not used of the reason, or mind, but of the WORD; the preceding context requires that "the word" should be meant here; the adjective "logikos" follows the meaning of the noun logos, "word." Jas 1:21, "Lay apart all filthiness … and receive with meekness the engrafted WORD," is exactly parallel, and confirms English Version here.
grow—The oldest manuscripts and versions read, "grow unto salvation." Being BORN again unto salvation, we are also to grow unto salvation. The end to which growth leads is perfected salvation. "Growth is the measure of the fulness of that, not only rescue from destruction, but positive blessedness, which is implied in salvation" [Alford].
thereby—Greek, "in it"; fed on it; in its strength (Ac 11:14). "The word is to be desired with appetite as the cause of life, to be swallowed in the hearing, to be chewed as cud is by rumination with the understanding, and to be digested by faith" [Tertullian].
