According to the Bible, the symbolism of baptism declares that three things happen to believers who are baptized: (1) they die with Christ to their old self; (2) they rise with Christ to become a new creature; and (3) they are incorporated in their new life with a living community which looks for the coming of the Lord (Romans 6:1-11). Contrary to what some denominations teach, it seems obvious that a Christian’s baptism must necessarily require a responsible decision to accept Jesus Christ as Savior and Lord, and therefore, must be delayed until an age of reason or discretion (knowing right from wrong within God’s perspective).
In short, Jesus Christ commands baptism for His followers. Although the act of baptism does not cause eternal salvation, it seems that any believer who refuses baptism should truly examine his or her conversion.
“Then Jesus came to them and said, ‘All authority in heaven and on earth has been given to me. Therefore, go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I will be with you always, to the very end of the age'” (Matthew 28:18-20).
