What does baptism represent in Christianity?

In Christianity, baptism serves as a profound representation of what has transpired in the believer's life through faith in Christ. It signifies the death of the old self and the birth of a new life in Christ. Romans 6:4 states, 'Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.' This passage illustrates that baptism is not just an outward action, but it intimately connects the believer to the life, death, and resurrection of Jesus. When one is immersed in water, it publicly displays this spiritual reality of being united with Christ, affirming that all hope of salvation is found in Him alone.
