Do What You Can; Trust God With The Rest

God grant me the serenity
To accept the things I cannot change;
the courage to change the things I can;
and the wisdom to know the difference.
- Reinhold Niebuhr (Serenity Prayer)

Make the best use of what is in your power,
and take the rest as it happens.
- Epictetus

Do what you can, and do it well.
Accept the rest with equanimity, and trust in God.
No one can ever do more than that.
- Jonathan Lockwood Huie
