This sermon explores the origins and significance of baptism and communion, tracing them back to their roots in the Exodus story.

Key Points

1. Communion: The Passover Fulfilled To understand the Last Supper, we must understand the First Supper (Passover). In Exodus 12, God provided a substitute (a lamb) to save the Israelites from judgment. This lamb had to be:
   • Pure: Without defect.
   • Personal: Kept in the home for four days.
   • Killed: A true sacrifice.
   • Applied: Blood on the doorposts (faith in action).
   • Consumed: Totally devoured (we take all of Jesus).
   • Taken in Faith: Eaten in haste, ready to move. Jesus is the fulfillment of this Passover lamb. He is the pure, personal sacrifice whose blood is applied to our lives, saving us from judgment.
2. Baptism: The Red Sea Crossing Baptism is framed by the Israelites' crossing of the Red Sea (Exodus 14). It involves three movements of salvation:
   • Leaving the Old Behind: Just as Israel left 430 years of slavery in Egypt, baptism symbolizes leaving our old life of bondage.
   • Surrendering to God: At the Red Sea, Israel was trapped and terrified. Moses told them, "The Lord will fight for you; you need only to be still." Baptism declares our trust in God to fight battles we cannot win.
   • New Identity: Passing through the waters, Israel was born again as a free nation. They emerged on the other side with a new identity as worshipers, erupting in song. Baptism marks our entry into a new life and identity in Christ.
3. Why We Do It We practice baptism and communion because Jesus commanded them, the early church practiced them, and they powerfully reenact the story of our salvation. They are not just rituals; they are "sacraments" that mark the church and remind us of who we are and whose we are.

Conclusion

The sacraments of baptism and communion are God's way of "resetting our clocks" and marking us as His own. Just as the Passover changed the calendar for Israel, meeting Jesus changes everything for us. We leave behind the old, trust God to fight for us, and step into a new identity as His people.

Calls to Action

1. Remember Your Baptism: If you are a believer, recall the moment you "crossed the Red Sea" and left your old life behind.
2. Take Communion in Faith: When you participate in the Lord's Supper, remember the cost of the Lamb and apply His blood to your life by faith.
3. Stand Firm: If you are facing an "impossible" Red Sea situation, hear the word of the Lord: "Do not be afraid. Stand firm... The Lord will fight for you; you need only to be still."
