Romans 8:10-11 If The Spirit Of Him That Raised Jesus From The Dead Dwell In You, He Shall Bring Life To Your Mortal Bodies

Romans 8:10-11 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness. But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.

This is a sure promise that we have trouble believing.
