Hereby know we that we dwell in him, and he in us, because he has given us of his Spirit.
Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
What? know you not that your body is the temple of the Holy Ghost which is in you, which you have of God, and you are not your own?
And hereby we do know that we know him, if we keep his commandments.
But whoever keeps his word, in him truly is the love of God perfected: hereby know we that we are in him.
And he that keeps his commandments dwells in him, and he in him. And hereby we know that he stays in us, by the Spirit which he has given us.
