God will fulfill all our needs

The church at Philippi had sent a gift to meet the needs of Paul. The Philippians were obedient to the Gospel, they were obedient to the demands of love for Paul, and they were obedient in their obligation to God’s servant. Paul's response (by means of his in faith in God) was as follows;
Php 4:19 KJV
(19) But my God shall supply all your need according to his riches in glory by Christ Jesus.

There is no promise that God shall supply all our desires or wishes, but there is a certainty that He will fulfill all our needs.

KJV Commentary has an excellent summation of this section;

We see first of all in this verse a great need. God promises to meet all of their (our) need, not all of their wishes, wants, or whims. Men have physical needs, mental needs, social needs, economic needs. Men have not only temporal needs, but spiritual and eternal needs. Men need perpetual pardon, perpetual peace, and perpetual power.

Secondly, we see in this verse a great helper. Paul says "But my God". Paul could not repay the Philippians, but God could and would. Paul does not say my God can supply all your needs, but my God shall supply all your needs. This was Paul’s personal testimony and confession of faith.

We see next a great Supplier. There is a total supply for a total need. God’s supply is infinite, abundant, inexhaustible, limitless, boundless. God many times uses the agencies of men to meet our needs.

Next we see great resources. God’s riches in glory. Paul says according to his riches, not out of His riches, not off the top. God’s supply is not according to our deserts, but according to His mercy; not out of debt, but out of grace; not according to our emptiness, but according to His fullness; not according to our poverty, but according to His wealth. God has great riches.

Lastly, look at the great and glorious channel by Christ Jesus. "For there is one God, and one mediator between God and men, the man Christ Jesus. There is no other Mediator; there is no other channel.

With such precious truth before us then there can only be concurrence with the past, contentment with the present, and confidence for the future
