What is the relationship between faith and baptism in Christianity?

The relationship between faith and baptism is foundational in Christian doctrine and practice. As seen in Acts 2:38, Peter calls for both repentance and baptism in the name of Jesus Christ for the remission of sins. In this context, baptism is a public declaration of faith, symbolizing the believer's identification with Christ's death, burial, and resurrection. It signifies the inward transformation that faith brings—a response to the grace of God. Furthermore, as Paul clarifies in his letters, baptism is an expression of the believer's faith, and those who are baptized publicly affirm their trust in Christ as their Savior. Thus, baptism is both an act of obedience to Christ’s command and a means of confirming one’s commitment to live in accordance with the truth of the Gospel.
