Pastor Jamie Self’s sermon explores the biblical depth of believer’s baptism as a public, covenantal sign of regeneration and church membership. Framing baptism within the grand narrative of redemption—creation, fall, redemption, and restoration—he shows how baptism functions as a visible sign of the New Covenant, signifying inward transformation and belonging to God’s people. Through the testimonies of Lily and JT, Pastor Self emphasizes baptism not merely as ritual but as a solemn oath of faith, accountability, and commissioning into the life and mission of the church.
