Christian churches use baptism as a symbol for a persons declaration of faith in Jesus Christ and their commitment to the repentance of sins. Churches regard this as a sacred ritual ordained by God. Water has always represented purification in any religion. In Christianity, a new believer often is baptized with water in front of the congregation to declare their faith in God. Even Jesus was baptized before the start of his public ministry to the world. Before Jesus ascended into heaven, he commanded all his disciples to baptize all the nations for the glory of God.
