Paul is in prison, but does not complain.
Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content.
12 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.
13 I can do all things through Christ which strengtheneth me. Philippians 4:11 – 13
In Christ we can do all things.
