Philippians 4:7, 11-12

And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.

Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content. I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need.
