Romans 8:9

Such is not your case — if at least the Spirit of God and of Christ dwells in you, as it should in every Christian.

The Spirit of God ... the Spirit of Christ. — It is to be observed that these two terms are used as convertible. The Spirit of Christ is indeed the presence of Christ Himself in the soul. (Comp. John 14:16; John 14:18; John 14:20, “I will pray the Father, and He shall give you another Comforter, that He may abide with you for ever.... I will not leave you comfortless (orphans): I will come to you.... At that day ye shall know that I am in My Father, and ye in Me, and I in you.”)

Dwell in you. — This expression is the complement of the other “to be in the Spirit,” “to be in Christ.” It denotes the closest possible contact and influence of spirit upon spirit. No mysticism, however vivid and intense, can really go beyond this without infringing the bounds of personality, and contradicting the direct testimony of consciousness.
