And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies through his Spirit, who lives in you. —Romans 8:11.
If we belong to Christ, we know the Spirit of God lives in us (Romans 8:9). Because of the Spirit’s presence, we know that we are eternal! The Spirit is God’s down payment, guaranteeing that our future is with him (2 Corinthians 1:21-22; 2 Corinthians 5:5). What’s more, even while we’re living for Christ now, the Spirit gives life to our physical bodies as we use them for God’s glory (Romans 12:1). He will do this until the time the Spirit raises us from our physical death and brings us into the eternal presence of God in our immortal bodies (1 Corinthians 15:50-58).
