Incarnation & Inhabitation
Just as in eternity God acted like Himself and when incarnated in human flesh still continued in all His conduct to be true to His holiness, so does He when He enters the nature of a believing man. This is the method by which He makes the redeemed man holy. He enters a human nature at regeneration as He once entered human nature at the incarnation and acts as becomes God, using that nature as a medium of expression for His moral perfections.
– A. W. Tozer, Of God and Men
The carnal attitude sees no further than natural things. But the spiritual attitude reaches out after the things of the spirit. The former attitude means, bluntly, death: the latter means life and inward peace. And this is only to be expected, for the carnal attitude is inevitably opposed to the purpose of God, and neither can nor will follow his laws for living. Men who hold this attitude cannot possibly please God.
But you are not carnal but spiritual if the Spirit of God finds a home within you. You cannot, indeed, be a Christian at all unless you have something of his Spirit in you. Now if Christ does live within you his presence means that your sinful nature is dead, but your spirit becomes alive because of the righteousness he brings with him. I said that our nature is “dead” in the presence of Christ, and so it is, because of its sin. Nevertheless once the Spirit of him who raised Jesus from the dead lives within you he will, by that same Spirit, bring to your whole being new strength and vitality.
So then, my brothers, you can see that we have no particular reason to feel grateful to our sensual nature, or to live life on the level of the instincts. Indeed that way of living leads to certain spiritual death. But if on the other hand you cut the nerve of your instinctive actions by obeying the Spirit, you are on the way to real living.
All who follow the leading of God’s Spirit are God’s own sons. Nor are you meant to relapse into the old slavish attitude of fear—you have been adopted into the very family circle of God and you can say with a full heart, “Father, my Father”. The Spirit himself endorses our inward conviction that we really are the children of God. Think what that means. If we are his children we share his treasures, and all that Christ claims as his will belong to all of us as well! Yes, if we share in his suffering we shall certainly share in his glory.
– Romans 8:5-17 (Phillips)
