Why is believers' baptism significant?

Believers' baptism, as discussed in 1 Peter 3:21, serves as a vital symbol representing an individual's public confession of faith. It does not wash away sins, rather, it signifies the believer's acknowledgment that they have been spiritually united with Christ—crucified, buried, and raised again. This act fulfills Jesus' command to go and make disciples, demonstrating one’s identification with Him. Moreover, the act of baptism symbolizes the inward reality of salvation that has already occurred through faith. Water baptism is not the means of salvation itself but a declaration of what has been accomplished through faith in Christ.
