“The waters saw you, O God, the waters saw you and writhed; the very depths were convulsed. The clouds poured down water, the skies resounded with thunder; your arrows flashed back and forth. Your thunder was heard in the whirlwind, your lightning lit up the world; the earth trembled and quaked. Your path led through the sea, your way through the mighty waters, though your footprints were not seen. You led your people like a flock by the hand of Moses and Aaron.” — Psalm 77:16-20
This entire psalm is dedicated to remembering the great deeds of the Lord for the Israelites. Specifically, they are remembering the exodus from Egypt, and how the Lord delivered them over and over again, even when faced with impossible odds and impossible situations.
Why is this important to remember hundreds of years later? God did amazing works throughout the Bible, most notably, He gave salvation to the Israelites over and over again. But the exodus story was special, I believe, because it so closely resembles our own deliverance through the gospel story of Jesus. The Israelites were slaves to an evil ruler and culture, but God sent a man to deliver them – Moses. He led them out of the corruption, and, though chased by Pharaoh's men, they passed through a miraculous water experience when the Red Sea was parted for them. When they came out on the other side, God eventually prepared for them and led them to a paradise. Isn't this just like our gospel story of being enslaved to sin, finding a Savior in the man Jesus Christ, being made new through the act of baptism, and striving for a while to eventually find life eternal with the Lord in heaven? This parallel is no coincidence. I believe that the Lord planned it to be just this way.
