Philippians 4:11-13
Not that I am referring to being in need; for I have learned to be content with whatever I have. I know what it is to have little, and I know what it is to have plenty. In any and all circumstances I have learned the secret of being well-fed and of going hungry, of having plenty and of being in need. I can do all things through him who strengthens me.

I often speak of those who complain about the hand they were dealt in this game we call life, rather than giving thanks that they were invited to the table to play at all! When and where did you learn how to be content with what you have?
