Scriptural baptism shows the growth of a Church, both in numbers and in maturity. A Church that is not baptizing people, has stagnated, and is not obedient to the Great Commission. Scriptural baptism pleases the Lord, because it recognizes the authority of the Church. Baptism can only be administered on the authority of a New Testament Church, and that authority comes directly from the Lord Jesus Christ. When He gave the Great Commission, He gave it to the Church, not to an individual.
Scriptural baptism guarantees the continuity of a church.
Through baptism, the church receives new life, new blood, and this assures its continued existence. The purpose of baptism is not for salvation, as some suppose. Indeed, you cannot have scriptural baptism until the person to be baptized has been saved. If the candidate for baptism has not been saved when he enters the baptistry, he goes into the water a dry sinner, and comes up out of the water a wet sinner. In this case scriptural baptism has not taken place.
