Why is water baptism essential for Christians?

Water baptism serves as an essential ordinance for Christians, symbolizing the believer's identification with the death, burial, and resurrection of Jesus Christ. It is an outward, physical representation of an inward spiritual reality, indicating that the individual has repented and is now part of the body of Christ. Jesus instructed His followers to be baptized as an act of obedience (Matthew 28:19-20), and through this act, believers publicly declare their faith and the transformative work of the Holy Spirit in their lives. Thus, water baptism not only fulfills a command of Christ but also serves to strengthen the community of faith as the church witnesses and supports the baptismal candidates.
