When his hope is at a loss, he doth but exercise his memory a little, and he recovers himself presently, and chides himself for his weakness. “I said, this is my infirmity: but I will remember the years of the right hand of the Most High.” The hound, when he hath lost the scent, hunts backward and so recovers it, and pursues his game with louder cry than ever. Thus, Christian, when thy hope is at a loss, and thou questionest thy salvation in another world, then look backward and see what God hath already done for thee. Some promises have their day of payment here, and others we must stay to receive in heaven.
William Gurnall commenting on Psalm 77:11
Psalm 77:11 (ESV)
11 I will remember the deeds of the Lord;
yes, I will remember your wonders of old.
