Philippians 4:19:

But my God shall supply all your need according to his riches in glory by Christ Jesus.

Notes on Philippians 4:19:

The immediate context here is finances, but meeting “all” your need would include any need you have for healing.  God considers healing a need in light of Luke 9:11, where Jesus healed those who “had need of healing.”

Contrary to the impression many people have, this verse does not mean that Jesus will take something in heaven (which they see as the meaning of “glory”) and use it to meet your need.  The end of this verse can also be translated “in Christ Jesus” and the point is that your needs are already met in Christ.  So when God meets your need, He is simply releasing something that is already earmarked for you based on His covenant.  He is not whipping up some new provision that wasn’t there before.
