This plain, simple verse, has been twisted by some who believe in the doctrine of perfection, and they have made it declare that it is possible for some to abide in Christ, and therefore not to sin. Whosoever abideth in him sinneth not. In reading the Bible, we read it simply as we would read another book. Now we are sure that cannot mean that he does not sin at all, but it means that sins not habitually, he sins not designedly, he sins not finally, so as to perish. That is the sign of it.
Works are the fruits of grace.
It will not allow our righteousness to be our own, but it brings us to Christ again. He that doeth righteousness is righteous, even as he is righteous. For this purpose the Son of God was manifested, that he might destroy the works of the devil. The best evidence is the salvation of the soul. For this purpose the Son of God was manifested, that he mighty destroy the works of the devil.
