1 Chronicles 19:13 Be strong, and let us use our strength for our people and for the cities of our God, and may the Lord do what seems good to him.
Keith Green used to sing:
So keep doing your best
And pray that it's blest
And He'll take care of the rest.
Lord, help us to do all within our power to fight for your kingdom, but in the end our prayer is that You will do what seems good to You.
