Philippians 4:10-13

But I rejoice in the Lord greatly that now at length you have revived your thought for me; in which you did indeed take thought, but you lacked opportunity. Not that I speak because of lack, for I have learnt in whatever state I am, to be content in it. I know how to be humbled, and I also know how to abound. In any and all circumstances I have learnt the secret both to be filled and to be hungry, both to abound and to be in need. I can do all things through Christ who strengthens me.
