Philippians 4:10-13

10 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.  11 Not that I speak in respect to lack, for I have learned in whatever state I am, to be content in it.  12 I know how to be humbled, and I know also how to abound. In everything and in all things I have learned the secret both to be filled and to be hungry, both to abound and to be in need.  13 I can do all things through Christ, who strengthens me.
