When John the Baptist appeared preaching his message of repentance; he introduced something totally new-water baptism- and it became a profession of commitment to change. This baptism was an outward expression of faith, a public testimony to the fact that one’s mind had changed about Jesus and was willing to acknowledge Him as the Savior. Water Baptism is a doctrine of the Church, and since we belong to Christ by right of blood purchase, it is incumbent upon every believer to adhere to this doctrine.
