The book of Exodus is a mere shadow pointing to the greater substance of Jesus Christ. It is all about the gospel and redemption. God pursues His people who are enslaved and provides a substitute death for them that gives them life. Then He miraculously delivers them out of that slavery into a new life of freedom to serve Him. They struggle in the wilderness for a bit, but God eventually brings them home to the Promised Land. As powerful as that was 3500 years ago, it parallels God’s faithfulness and what Christ did to fully and completely redeem us.
