2:24-29 The truth of Christ, abiding in us, is a means to sever from sin, and unites us to the Son of God, Joh 15:3,4. What value should we put upon gospel truth! Thereby the promise of eternal life is made sure. The promise God makes, is suitable to his own greatness, power, and goodness; it is eternal life. The Spirit of truth will not lie; and he teaches all things in the present dispensation, all things necessary to our knowledge of God in Christ, and their glory in the gospel. The apostle repeats the kind words, little children; which denotes his affection. He would persuade by love. Gospel privileges oblige to gospel duties; and those anointed by the Lord Jesus abide with him. The new spiritual nature is from the Lord Christ. He that is constant to the practice of religion in trying times, shows that he is born from above, from the Lord Christ. Then, let us beware of holding the truth in unrighteousness, remembering that those only are born of God, who bear his holy image, and walk in his most righteous ways.

abideth in you—He tacitly thus admonishes them to say, when tempted by seducers, "The anointing abideth in us; we do not need a teacher [for we have the Holy Spirit as our teacher, Jer 31:34; Joh 6:45; 16:13]; it teaches us the truth; in that teaching we will abide" [Bengel].

and—and therefore. God is sufficient for them who are taught of Him; they are independent of all others, though, of course, not declining the Christian counsel of faithful ministers. "Mutual communication is not set aside, but approved of, in the case of those who are partakers of the anointing in one body" [Bengel].

the same anointing—which ye once for all received, and which now still abides in you.

of—"concerning."

all things—essential to salvation; the point under discussion. Not that the believer is made infallible, for no believer here receives the Spirit in all its fulness, but only the measure needful for keeping him from soul-destroying error. So the Church, though having the Spirit in her, is not infallible (for many fallible members can never make an infallible whole), but is kept from ever wholly losing the saving truth.

no lie—as Antichristian teaching.

ye shall abide in him—(1Jo 2:24, end); even as "the anointing abideth in you." The oldest manuscripts read the imperative, "abide in Him."
