“And my God will meet all your needs according to his glorious riches in Christ Jesus.” (Philippians 4:19)
Here we have the promise that God will supply our needs out his abundant riches. Consider the context. Paul has just told them that he knows what it is to be in need, including being hungry. In fact, this passage is triggered when the Philippian church sends Paul an offering that arrives in a time of considerable need.
If we expand the situation a bit, we find that the church at Philippi is concerned about Paul and his condition. They decide to send Paul an offering – however, to send it they have to send money that they, themselves, need for their daily needs. However, they send it anyway and it greatly encourages Paul.
Paul writes to them and says, “I know you sent money you didn’t really have to send, but I believe the Lord has taken note of what you have done and that he will take care of you even as you have taken care of me.”
The promise of this verse is that if I empty out my bank account for a need that the Lord has laid on my heart, I can do so in faith that God will meet the needs of my life.
