Philippians 4:10-13

It is a great joy to me in the Lord that at long last you have renewed your concern for me. Of course you have always been concerned, but without opportunity to show it. I am not saying this because I am in need, for I have learned to be content whatever my circumstances. I know what it is to be in need, and I know what it is to be in prosperity. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living with plenty or in need: I can do all things through him who gives me strength.
