Knowing how to live - no matter what

I know how to live in humble circumstances;
I know also how to live with abundance.

In every circumstance and in all things
I have learned the secret of being well fed
and of going hungry,
of living in abundance
and of being in need.

I can do all things
in him who strengthens me.

(from today's Epistle - Phillipians 4:12-14, 19-20)
