“You, however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him. But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.”
Paul’s treatment of the Spirit’s work is rich and nuanced in this text. Four times in three verses he uses language that firmly establishes the Spirit’s vocation of indwelling the believer.
We learn five important things about indwelling from this text. First, Paul connects being “in” the Spirit with indwelling. The man who has the Spirit residing in him is always “in” the Spirit. This is a static reality, one does not move in and out of the Spirit.
Second, an inextricable link is made between the Spirit and Christ. Paul identifies the third person of the Trinity as the Spirit of Christ. He also equates Spirit’s indwelling work with Christ’s presence in us. The Spirit mediates the presence and purposes of Christ within us.
Third, indwelling is equated with belonging. The Spirit’s presence in our lives communicates divine ownership. When God takes up residence in us by the Spirit we are secure in our adoption. The permanence of his new residence means that God will never leave or forsake us.
Fourth, the Spirit works life and righteousness in us in spite of our sin. The indwelling presence of God is a mighty force working our transformation. Change is inevitable for the person who has become the home of God.
Fifth, the promise of our resurrection is tied to the indwelling Spirit. The text’s logic draws a link between the Spirit who raised Christ from the grave and that same Spirit who dwells in us. If he raised Christ, it is certain, he will raise us as well.
Resurrection, transformation, and belonging, these all flow from the Spirit’s indwelling presence. The Spirit of Christ mediates the purposes and presence of Jesus in our lives. Paul helps us understand that being “in” the Spirit is the same as having the Spirit live within us.
In this text alone we see the significance of indwelling. Our current transformation, our future hope, and our status before God are all dependent upon it. We cannot overstate the importance of the Holy Spirit making his home in us.
