Baptism is more than a celebration of a decision we made. Scripture presents it as a rich, visible declaration of what God has done for us in Christ. In this sermon, we look at four ways the Bible teaches us to understand baptism: as a reenactment of a spiritual reality, a renaming ceremony, an ordination into a royal priesthood, and a means of grace that strengthens and assures us. Baptism reenacts our union with Christ in his death and resurrection. We go under the water because, in Christ, we have gone under judgment, and we come up because we have been raised to new life. Like Passover, the Lord’s Supper, the flood, and the Red Sea, baptism points us away from our accomplishment and toward God’s saving action. It is also a renaming ceremony. In baptism, we are publicly marked as belonging to the Father, Son, and Holy Spirit. We are transferred from the kingdom of darkness into the kingdom of Christ, adopted into God’s family, and welcomed into the visible church. Our identity is no longer grounded in who we were, but in whose name has been placed upon us. Baptism also reminds us that we have been set apart as a royal priesthood. We do not represent Christ because we are especially qualified, impressive, or spiritually accomplished. We represent him because he has qualified us. Our confidence is not in our own fitness for the task, but in the righteousness of Christ into whom we have been baptized. And finally, baptism is meant to strengthen our souls. The water does not save us, but it visibly proclaims the cleansing, regeneration, adoption, and Spirit-given life that belong to us by faith in Christ. When we are discouraged, ashamed, or overwhelmed by our failures, we can remember our baptism and everything it declares: we have been washed, named, adopted, united to Christ, and welcomed to draw near to God with full assurance. Baptism is not ultimately about what we have decided to do for God. It is about what God has done for us.
