Water baptism holds a significant purpose in salvation, yet is not mandatory for eternal life and fellowship with God. It is an outward sign of an inward change of heart. This change happens when one receives Jesus as Lord and Savior and it is what is called the New Birth. Water baptism, signifying burial with Christ and resurrection to a new life, should be observed as commanded in Holy Scriptures by all who have repented of sin and, in their hearts, have truly believed in Jesus Christ as their Savior and Lord.
Acts 8:35-39, Romans 6:3-4
