Philippians 4:10, 12, 14

I rejoiced greatly in the Lord that at last you renewed your concern for me. Indeed, you were concerned, but you had no opportunity to show it.

I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want.

Yet it was good of you to share in my troubles.
