John Gill defends the practice of baptism by immersion, arguing against a recent pamphlet that promotes alternative methods. He emphasizes that the scriptural basis for baptism is rooted in the examples of Jesus and the apostles, who practiced immersion, and he critiques the opposing views as lacking in scriptural support. Gill asserts that the act of baptism symbolizes the burial and resurrection of Christ, which necessitates immersion to accurately represent this significance. He challenges the arguments of his opponent, Mr. B.W., highlighting the importance of adhering to biblical principles in the administration of baptism.

Zac Poonen emphasizes the significance of baptism as an immersion in water, rooted in the original Greek meaning of the word 'baptism' which is derived from 'bapto', meaning to cover wholly with a fluid. He illustrates that both the baptism of Jesus and the Ethiopian eunuch involved going down into the water and coming up out of it, reinforcing that true baptism is a complete immersion rather than a mere sprinkling. Poonen argues that baptism symbolizes a burial, which can only be accurately represented through immersion, and highlights that only those who have died to their old selves, desiring to turn away from sin, are eligible for baptism.
