The purpose of baptism is to serve as a public declaration of faith and a symbolic representation of a believer's spiritual transformation. While specific interpretations vary across denominations, it is widely viewed as a foundational act of obedience to the commands of Jesus Christ.

Core Purposes of Baptism
- Public Profession of Faith: Baptism acts as an outward sign of an inward reality. Like a "team jersey" or a wedding ring, it tells the world that the individual has committed to following Jesus.
- Identification with Christ: The physical act of immersion is a vivid picture of the Gospel.
- Going under water represents dying to the "old self" and sin.
- Rising from water symbolizes being raised to a "new life" through Christ's resurrection.
- Act of Obedience: Many believers get baptized simply because Jesus commanded it in the "Great Commission" (Matthew 28:19) and provided an example by being baptized himself by John the Baptist.
- Entrance into the Community: It serves as a rite of initiation, marking the believer's formal entry into the local and universal "body of Christ"—the church.
- Symbol of Cleansing: The use of water signifies the washing away of sins and spiritual purification.
