1 John 3:24 Updated American Standard Version (UASV) 24 And the one who keeps his commandments remains in him, and he in him. And by this we know that he resides in us: by the Spirit whom he has given to us.

Those who love God must live as he wants them to live. They must not go on sinning; rather, they must love their brothers in Christ not just in words but also in deeds.
