What the presence of Christ within means

^9-11 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.

^12-13 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.

Christ is within—follow the lead of his Spirit

^14-17 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.

4 ^1-7 But you must realise that so long as an heir is a child, though he is destined to be master of everything, he is, in practice, no different from a servant. He has to obey a guardian or trustee until the time which his father has chosen for him to receive his inheritance. So is it with us: while we were “children” we lived under the authority of basic moral principles. But when the proper time came God sent his son, born of a human mother and born under the jurisdiction of the Law, that he might redeem those who were under the authority of the Law and lead us into becoming, by adoption, true sons of God. It is because you really are his sons that God has sent the Spirit of his Son into your hearts to cry “Father, dear Father”. You, my brother, are not a servant any longer; you are a son. And, if you are a son, then you are certainly an heir of God through Christ.
