The first is administered once, and the second is observed by the believer often. Through baptism, the Christian confesses his identification with the Lord Jesus Christ in His death, and determines to follow Him and walk in newness of life. Scripture does not teach of baptism before profession of faith. Such obedience brings great joy. But there is no basis for infant baptism.
Baptism is conditional on believing which comes through an intelligent hearing of the gospel.
Baptism should not be regarded as a non-essential because it does not affect one's salvation. Since it is a distinct command of the Lord Jesus, then it is necessary for complete obedience. While stressing the importance of baptism by immersion, it should not be made the basis for participation at the Lord's supper or fellowship with other believers. Some may not have seen this distinctive truth or still be under the authority of a parent who prevents them doing so. Today, we live in conditions never envisaged in the N.T. where we have a baptised mass of humanity as a result of their being christened.
