Baptism shows the world that you have given over your life to Jesus Christ. Paul writes to the Corinthians, “If anyone is in Christ, he is a new creature; the old things passes away; behold new things have come.” (2 Corinthians 5:7) It indicates that you have died to self, been buried in Christ, and raised to a new life in Him. Baptism declares to the world that you are a new creation in Christ Jesus.
