In Matthew 28:19, Jesus commands His followers, “go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” Baptism does not provide salvation for an individual, but rather serves to identify publicly the individual as a follower of Christ.
In passages such as Acts 2:41, 8:12, and 10:47-48, the act of Baptism follows an individual’s decision to trust in Jesus Christ alone for salvation. In Romans 6:1-11, the apostle Paul describes the immersion of Baptism as a means through which the believer identifies with the death, burial, and resurrection of Jesus Christ: Going under the water represents Christ’s death and a believer’s death to sin; coming out of the water illustrates His resurrection and the believer’s new life in Christ.
Baptism is an act of obedience to Christ that follows an individual’s acceptance of salvation by God’s grace alone. Baptism isn’t a prerequisite for salvation; however, if an inner commitment to trust Christ alone for salvation has been made, then the outward symbol of that commitment Baptism should follow, as is modeled throughout the New Testament in the lives of those choosing to follow Christ.
