And I will put My spirit within you, and cause you to walk in My statutes, and ye shall keep My judgments, and do them. – Ezekiel 36:27

Now when God’s own Spirit comes to reside within our mortal bodies, how near akin we are to the Most High! “Know ye not that your body is the temple of the Holy Ghost?” Does not this make a man sublime? Have you never stood in awe of your own selves, O ye believers? Have you enough regarded even this poor body, as being sanctified and dedicated, and elevated into a sacred condition, by being set apart to be the temple of the Holy Ghost? Thus are we brought into the closest union with God that we can well conceive of. Thus is the Lord our light and our life; while our spirit is subordinated to the divine Spirit. “I will put My spirit within you”-then God Himself dwelleth in you. The Spirit of Him that raised up Christ from the dead is in you. With Christ in God your life is hid, and the Spirit seals you, anoints you, and abides in you. By the Spirit we have access to the Father; by the Spirit we perceive our adoption, and learn to cry, “Abba, Father”; by the Spirit we are made partakers of the divine nature, and have communion with the thrice holy Lord.

I cannot help adding here that it is a very condescending word- “I will put My spirit within you.” Is it really so, that the Spirit of God who displays the power and energetic force of God, by whom God’s Word is carried into effect- that the Spirit who of old moved upon the face of the waters, and brought order and life from chaos and death- can it be so that He will deign to sojourn in men?

“A sinner is a sacred thing,
The Holy Ghost hath made him so.”
