359. Man cannot be an image of God, after His likeness, unless God is in him and is his life from the inmost. That God is in man and, from the inmost, is his life, follows from what has been shown above (n. 4-6), that God alone is life, and that men and angels are recipients of life from Him. Moreover, that God is in man and that He makes His abode with him, is known from the Word; for which reason it is customary for preachers to declare that men ought to prepare themselves to receive God, that He may enter into them, and be in their hearts, that they may be His dwelling-place. The devout man says the same in his prayers, and some speak more openly respecting the Holy Spirit, which they believe to be in them when they are in holy zeal, and from that zeal they think, speak, and preach. That the Holy Spirit is the Lord, and not a God who is a person by Himself, has been shown in The Doctrine of the New Jerusalem Concerning the Lord (n. 51-53). For the Lord declares:
In that day ye shall know that ye are in Me, and I in you (John 14:20; so also in chap. 15:4, 5; and chap. 17:23).
