1Jn 2:29 ".......every one that doeth righteousness is born of him. "

1Jn 2:21    I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.

1Jn 2:22    Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.

1Jn 2:23    Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also.

1Jn 2:24    Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father.

1Jn 2:25    And this is the promise that he hath promised us, even eternal life.

1Jn 2:26    These things have I written unto you concerning them that seduce you.

1Jn 2:27    But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.

1Jn 2:28    And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming.

1Jn 2:29    If ye know that he is righteous, ye know that every one that doeth righteousness is born of him.

This builds on the idea in my last post.

There is an exclusionary nature to the faith as well as an openness. 

One gets a flavor of this in other verses.

Mat 7:13    Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:

Mat 7:14    Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.

Mat 7:15    Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

Mat 7:16    Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?

Mat 7:17    Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.

Mat 7:18    A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.

Mat 7:19    Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.

Mat 7:20    Wherefore by their fruits ye shall know them.

Mat 7:21    Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.

Mat 7:22    Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?

Mat 7:23    And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Rom 3:10    As it is written, There is none righteous, no, not one:

Rom 3:11    There is none that understandeth, there is none that seeketh after God.

Rom 3:12    They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.

Psa 14:1    To the chief Musician, A Psalm of David. The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.

Psa 14:2    The LORD looked down from heaven upon the children of men, to see if there were any that did understand, and seek God.

Psa 14:3    They are all gone aside, they are all together become filthy: there is none that doeth good, no, not one.

1 John 2:29 Gill

If ye know that he is righteous,.... That is, Christ, who is righteous as God in his nature and in his works; and as man in his obedience, life, and conversation; and as Mediator, in faithfully discharging the work he undertook; and is the author of an everlasting righteousness, which is imputed by God, revealed in the Gospel, and received by faith; all which they knew, for this is not said as doubting, but rather as taking it for granted that they did know it; "if", or "seeing ye know", &c. then it follows;

ye know, or "know ye"; ye may assure yourselves,

that everyone that doeth righteousness; not merely works of righteousness, especially in order to justify him before God; for such an one is so far from being born of God, or born again, that he is manifestly in a state of nature, and of opposition to, and enmity against God; he is not subject to him, he does not submit to the righteousness of God, but goes about to establish his own and betrays his ignorance and want grace; but it intends such an one who with the heart believes unto righteousness, and lays hold by faith, and lives upon the righteousness of Christ for justification; and who performs, good, works in faith, and from a principle of love, not to obtain a justifying righteousness, but because he is justified by the righteousness of Christ: and: such an one

is born of him; either of God, or rather, of Christ; being regenerated by his Spirit, having his, grace implanted in him, as appears by his faith in his righteousness and by his works of righteousness, as fruits of faith; and having his image stamped on him, and he himself formed in him, and so made like unto him; by all which it is evident he is one of his spiritual seed and offspring. The Syriac version reads, "is of him"; belongs to him, is one of his; and this makes way for what is said of adoption in the following chapter and which should begin here.
