Lord, are my lamp; the Lord turns my darkness into light

2 Samuel 22:21-37
The Lord has dealt with me according to my righteousness; according to the cleanness of my hands he has rewarded me.
For I have kept the ways of the Lord; I am not guilty of turning from my God.
The Lord has rewarded me according to my righteousness,  according to my cleanness in his sight.
To the faithful you show yourself faithful, to the blameless you show yourself blameless, to the pure you show yourself pure,  but to the devious you show yourself shrewd.
As for God, his way is perfect:  The Lord’s word is flawless; he shields all who take refuge in him.
You, Lord, are my lamp;  the Lord turns my darkness into light.
Why?
David expresses the characters of the Lord he met.
God is righteousness and mercy.
My God, his way is perfect so I will obey him.
How?
Listen to God, obey his words and pray to the Lord, Praise be to the Lord!
