How do we know the importance of baptism?

Baptism holds deep significance in the life of a believer as it symbolizes the believer's union with Christ and publicly affirms their faith. As noted in the article, baptism is depicted not just as an individual act but as a collective, participatory act within the Body of Christ. It represents our commitment to live under the new covenant of grace, embracing the identity of being 'a chosen priesthood and holy nation.' This public declaration confronts the individual believer's past sins, acknowledging Christ's atoning work, and opens the way for living out the faith bestowed upon us. Hence, baptism is not merely a ritual but a profound statement of our identity in Christ.
