The psalmist begins with praise in verse 1, and then goes on to remember why it is right to praise God. God’s people have a history of sinning (verse 6), acting wickedly (verse 6) and forgetting God’s kindness (verse 7). And yet God led them out of Egypt and miraculously provided for them parting the Red Sea. Remembering God’s goodness and kindness to us is part of what we are called to do.
