Philippians 4:10-13 ESV
I rejoiced in the Lord greatly that now at length you have revived your concern for me. You were indeed concerned for me, but you had no opportunity.  Not that I am speaking of being in need, for I have learned in whatever situation I am to be content.  I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need.  I can do all things through him who strengthens me.
In times like the one we presently face, we are prone to be discontented. Our circumstances are not only unacceptable, they are intolerable. Our inability to be content serves only to exacerbate our misery.
