Answer me when I call, O God of my righteousness! You have given me relief when I was in distress. Be gracious to me and hear my prayer! (Psalm 4:1 ESV)
C. H. Spurgeon comments on Psalm 3 in the Treasury of David:
This is another instance of David’s common habit of pleading past mercies as a ground for present favour. Here he reviews his Ebenezers and takes comfort from them. It is not to be imagined that he who has helped us in six troubles will leave us in the seventh. God does nothing by halves, and he will never cease to help us until we cease to need.
