a Bible passage
24All who obey his commandments abide in him, and he abides in them. And by this we know that he abides in us, by the Spirit that he has given us.
24 And he that keepeth his commandments He confirms what I have already stated, that the union we have with God is evident when we entertain mutual love: not that our union begins thereby, but that it cannot be fruitless or without effect whenever it begins to exist. And he proves this by adding a reason, because God does not abide in us, except his Spirit dwells in us. But wherever the Spirit is, he necessarily manifests his power and efficiency. We hence readily conclude, that none abide in God and are united to him, but those who keep his commandments.
When, therefore, he says, and by this we know, the copulative, and, as a reason is here given, is to be rendered, “for,” or, “because.” But the character of the present reason ought to be considered; for though the sentence in words agrees with that of Paul, when he says that the Spirit testifies to our hearts that we are the children of God, and that we through him cry to God, Abba, Father, yet there is some difference in the sense; for Paul speaks of the certainty of gratuitous adoption, which the Spirit of God seals on our hearts; but John here regards the effects which the Spirit produces while dwelling in us, as Paul himself does, when he says, that those are God’s children who are led by the Spirit of God; for there also he is speaking of the mortification of the flesh and newness of life.
The sum of what is said is, that it hence appears that we are God’s children, that is, when his Spirit rules and governs our life. John at the same time teaches us, that whatever good works are done by us, proceed from the grace of the Spirit, and that the Spirit is not obtained by our righteousness, but is freely given to us.
