What does the Bible say about baptism and its significance?

Baptism, as described in Colossians 2:12, symbolizes the believer's union with Christ in His death and resurrection. It serves not as a means of salvation but as a public declaration of faith, demonstrating that a believer has been spiritually raised to new life in Christ. 1 Peter 3:21 further underscores that baptism is the answer of a good conscience towards God, showing that it is an expression of the faith granted to the believer by God's grace. Thus, while baptism is an important act of obedience and confession, it is essential to recognize that it does not contribute to salvation, which is entirely the work of Christ.
