But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you. Romans 8:11

Has this ever happened to you?  You arrive home from work on a Friday evening and carelessly leave the car door ajar, so the interior dome lights remain on. You don’t drive the car on Saturday, but Sunday morning you discover a dead battery. Only one thing will help: an infusion of electrical power from another source – provided graciously by your neighbor with his jumper cables.

Our life is somewhat analogous to the dead-battery situation. Paul writes that before knowing Christ we were “dead” in our sins (Ephesians 2:1, 5; Colossians 2:13). But then he writes that the same God that raised Jesus from the dead “will also give life to your mortal bodies through His Spirit who dwells in you.” That’s certainly going to happen at the resurrection, but it also happens now as our spiritually dead bodies have been given an infusion of God’s power, not only to bring us to new life (Romans 8:10-11), but to empower us to do all that He requires and requests of us.
           
Depend on the fact – (believe, trust) – that you have power from God today, by His Spirit who dwells in you, to overcome every challenge.
 
Christianity is not merely a program of conduct; it is the power of a new life.
– Benjamin B. Warfield
