"God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference." – Reinhold Niebuhr

I think "contentment" could be another synonym for serenity. The apostle Paul said he was content even though he had been beaten, imprisoned.....several times during his ministry.

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. I can do all things through Christ which strengtheneth me. Philippians 4:11-13
