Have mercy on me, for I am afflicted

 Turn Yourself to me, and have mercy on me, For I am desolate and afflicted. Psalm 25:16

The psalmist again makes the right argument for asking God's mercy; I am desolate and afflicted A merciful God cannot be indifferent to the prayer of a desolate and afflicted person. The psalmist is aware that while others might not sympathize with his sorrow, his God will, because His mercy endures forever. The psalmist knows God's compassionate heart, believes in His mercy, therefore he can pray like this.
