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" 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.
