What does it mean to remember God’s faithfulness?  To the Psalmists it not only meant remembering God’s personal faithfulness (Psalm 54:7) but also remembering the legacy of God’s faithfulness to countless others before them.

I will remember the deeds of the LORD;
yes, I will remember your wonders of old. . . .
You with your arm redeemed your people,
the children of Jacob and Joseph. . . .
You led your people like a flock
by the hand of Moses and Aaron (Psalm 77).

God has given us a rich history of his faithfulness to take confidence in.
