Philippians 4:10-12

10Now I rejoice greatly in the Lord that at last you have revived your concern for me. You were indeed concerned, but you had no opportunity to show it. 11I am not saying this out of need, for I have learned to be content regardless of my circumstances. 12I know how to live humbly, and I know how to abound. In any and every situation I have learned the secret of being filled and being hungry, of having plenty and having need.
