Philippians 4:10-13

But I rejoice in the Lord greatly, that now at length ye have revived your thought for me; wherein ye did indeed take thought, but ye lacked opportunity. Not that I speak in respect of want: for I have learned, in whatsoever state I am, therein to be content. I know how to be abased, and I know also how to abound: in everything and in all things have I learned the secret both to be filled and to be hungry, both to abound and to be in want. I can do all things in him that strengtheneth me.
