"I will remember the deeds of the Lord; yes, I will remember your wonders of old. I will ponder all your work, and meditate on your mighty deeds".
For the psalm-singer it's not enough that Israel has experienced the redemptive acts of Yahweh in the past. The writer wants to rehearse and re-live them in his own life. So he "remembers, calls to mind, considers thoughtfully" the mighty deeds of the Lord. This intellectual act of recollection immediately becomes the foundation of ravishing praise. The point is clear: remembering the mighty deeds of God is a symptom of delight in the fame of God. Praise also includes mental reconstruction of the past.
