"Ephesians 3:16-18 (New International Version)
16I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, 17so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love,"
In the Greek Word Study it says,
16 that he might give to you by the rich of the splendor of him power to be strengthened though the spirit of him into the inside man, 17 to reside the Christ though the trust in the hearts of you, in love having been rooted and having been founded,
It's not God in your body. It's the strength of His Spirit though trust, in your mind. Your mind is what it means when it says your heart.
