Verse 14. - The address to the fathers remains unchanged; their claim to Gospel and to Epistle is the same. The address to the young men is enlarged; their claim to the Gospel is that they are strong to fight, have God's revelation of himself as a permanent possession in their hearts, and have won victories over Satan. The context and John 5:38 and John 10:35 utterly forbid us from understanding ὁ λόγος τοῦ Θεοῦ of the "living Personal Lord" (cf. John 17:6, 14, 17; Revelation 1:9; Revelation 6:9; Revelation 20:4).

2:12-14 As Christians have their peculiar states, so they have peculiar duties; but there are precepts and obedience common to all, particularly mutual love, and contempt of the world. The youngest sincere disciple is pardoned: the communion of saints is attended with the forgiveness of sins. Those of the longest standing in Christ's school need further advice and instruction. Even fathers must be written unto, and preached unto; none are too old to learn. But especially young men in Christ Jesus, though they are arrived at strength of spirit and sound sense, and have successfully resisted first trials and temptations, breaking off bad habits and connexions, and entered in at the strait gate of true conversion. The different descriptions of Christians are again addressed. Children in Christ know that God is their Father; it is wisdom. Those advanced believers, who know Him that was from the beginning, before this world was made, may well be led thereby to give up this world. It will be the glory of young persons to be strong in Christ, and his grace. By the word of God they overcome the wicked one.I have written unto you, fathers,.... This, with the reason annexed to it, is repeated, to raise the attention of the aged servants of Christ, and to quicken them to a discharge of their duty, who are apt to abate in their zeal, to grow lukewarm and indifferent, to cleave to the world, and to the things of it, which they are cautioned against in 1 John 2:15. The whole of this, with the reason,

because ye have known him that is from the beginning, is left out in the Vulgate Latin version, and Complutensian edition.

I have written unto you, young men; this repetition to them, with some additions, is also made, to stir them up the more to love the saints, who are too apt to be carried away with the lust of the flesh, the lust of the eyes, and the pride of life, warned against in 1 John 2:16;

because ye are strong; not naturally, for sin has sadly weakened human nature, so that a man, by the strength of nature, can do nothing that is spiritually good: nor in themselves, though regenerated, but in Christ, in whom are righteousness and strength; without whom they can do nothing, though they can do all things through him strengthening them; and so are strong in the exercise of grace on him, and in the performance of every duty, being strengthened by him with strength in their souls:

and the word of God abideth in you; either Christ the Logos, the essential Word of God, who might be said to be in them, and abide in them, because his grace was implanted in their hearts, called Christ, formed there, and because he dwelt in their hearts by faith, and lived in them; and hence they had their strength, or came to be so strong as they were, and also overcame Satan, because he that was in them was greater than he that is in the world: or else the Gospel is meant, which cometh not in word only, but in power, has a place in the heart, and works effectually, and dwells richly there; and this is a means of spiritual strength against sin and temptation, and to perform duty, and to stand fast in the truth against the errors and heresies of men and is that piece of spiritual armour, the sword of the Spirit, by which Satan is often foiled, and overcome: hence it follows,

and ye have overcome the wicked one; See Gill on 1 John 2:13.
