What does immersion in baptism mean?

Immersion is the biblical mode of baptism as it signifies being fully submerged, which aligns with the meaning of the term 'baptism' itself. As illustrated in Acts 8:38-39, the act of going down into the water portrays the believer's identification with Christ's death and burial, while emerging from the water symbolizes His resurrection. This full immersion highlights the believer’s complete identification with the gospel, embodying the reality that they have been cleansed from sin and are called to live in newness of life.
