What does baptism signify in Christianity?

In Christianity, baptism is a physical manifestation of a spiritual reality. As mentioned in Romans 6:3-6, baptism symbolizes being buried with Christ in His death and being raised to walk in newness of life, reflecting the believer's identification with Christ's redemptive work. It serves as an outward sign of inward grace; through baptism, Christians declare their faith and commitment to follow Jesus. This ordinance is important as it represents obedience to Christ's command and acts as a public testimony of one’s faith and the transformative power of the gospel.
