O weary warrior, let go and let God!  This battle is not yours but the Lord’s.  Stand still and see His salvation!

Psalm 9:

 ¹I will praise thee, O LORD, with my whole heart; I will shew forth all thy marvellous works.

 ²I will be glad and rejoice in thee: I will sing praise to thy name, O thou most High.

 ³When mine enemies are turned back, they shall fall and perish at thy presence.

 ⁴For thou hast maintained my right and my cause; thou satest in the throne judging right.
