1 Chronicles 19:13

Be of good courage, and let us behave ourselves valiantly for our people, for very much depends upon the attitude of the leader in all great crises, and for the cities of our God, which would have been in danger of capture and destruction in case the enemies had gained the victory; and let the Lord do that which is good in His sight. This is the trust which should characterize all Christians. After they have done all that is in their power, and if they are straining all their strength, they may leave the success of their efforts to the Lord in prayerful confidence.
