Verse 25. - And the promise which he promised us is this, even the eternal life. Αὐτός is Christ; αὕτη looks forward to "the eternal life," not backwards to the abiding in the Father (John 3:16; John 5:24; John 6:40, 54). Τὴν ζωὴν τὴν αἰώνιον is in the accusative by attraction to ἥν. "What St. John would have us feel is this, that there can be no promise to compare with this - that we should share the eternal life, the life of God.... We often speak as if people were to be paid for being good; not as if the being good were itself God's highest gift and blessing" (Maurice). The reading ὑμῖν (B) for ἡμῖν is worthy of notice. In verses 16, 17 St. John gives two reasons for shunning the world: because

(1) the world is alien to the Father;

(2) it is passing away.

So here he gives two for holding fast the truth originally delivered to them: because the truth leads

(1) to fellowship with God;

(2) to eternal life.

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.And this is the promise that he hath promised us,.... Either God the Father, who is that God that cannot lie, who in the covenant of his grace, before the world began, made this promise unto his people,

even eternal life; which promise, with all others, was put into the hands of Christ, where, with them, it is yea and amen; and also the thing itself promised, where it is hid, and lies safe and secure: or the Son, the Lord Jesus Christ, who has promised it in the Gospel; for this is the sum of the Gospel declaration, that whoever believes in him shall have everlasting life; and this lies in the knowledge of the Father, and of the Son, and in the enjoyment of them, and conformity to them; wherefore the doctrine respecting them ought to be retained, and firmly adhered to.
