I will remember the deeds of the LORD; yes, I will remember your wonders of old. Psalm 77:11
Summary: After crying out to the Lord in prayer and not getting an answer, he remembers that, in the past, God had answered his prayers. It seemed that the skies were closed shut to his prayers. God was silent. The psalmist writes:
5 I think of the good old days, long since ended, 6 when my nights were filled with joyful songs. I search my soul and ponder the difference now.
