After a person has believed in Jesus Christ as the One who died to pay the penalty for sin and that He resurrected to guarantee our eternal life (Romans 10:9-10), it is natural for that individual to publicly declare their faith in Jesus Christ. Although there are many ways a person can demonstrate their faith in Jesus Christ, God ordained baptism as the means by which a new believer publicly shows his faith. New believers have been expressing their faith in Jesus Christ through baptism for nearly 2,000 years; in fact, the Apostle Peter preached a sermon to thousands of people in the first century and called on them to repent and believe in Jesus Christ (Acts 2:14-40). Those who believed were immediately baptized as an expression of their faith in Jesus (Acts 2:41).
