What does the Bible say about baptism?A Scripture-grounded answer about what does the bible say about baptism

Baptism in the Bible is an outward sign of an inward reality — a public declaration of faith in Christ's death, burial, and resurrection. Jesus commanded it in the Great Commission, and the early church practiced it immediately after conversion. Christians disagree on whether baptism is necessary for salvation or is an act of obedience following salvation. Most agree it symbolizes dying to sin, being buried with Christ, and rising to new life. The New Testament records both believer's baptism (Acts 2:41) and household baptisms (Acts 16:33).
