"...for the temple of God is holy, which temple ye are... And ye are Christ's, and Christ is God's" (1 Corinthians 3:17, 23)
Deity indwelling men! That, I say, is Christianity, and no man has experienced rightly the power of Christian belief until he has known this for himself as a living reality. Everything else is preliminary to this.
Incarnation, atonement, justification, regeneration - what are these but acts of God preparatory to the work of invading and the act of indwelling the redeemed human soul? Man, who moved out of the heart of God by sin, now moves back into the heart of God by redemption. God, who moved out of the heart of man because of sin, now enters again His ancient dwelling to drive out His enemies and once more make the place of His feet glorious.
Regeneration is like building a house and having the work done well. Sanctification is having the owner come and dwell in the house and fill it with gladness and life and beauty.
Shut in with Thee, O Lord, forever,
My wayward feet no more to roam;
What power from Thee my soul can server?
The center of God's will my home.
