Jesus placed salvation after baptism. It is to be administered in the name of the Father, and of the Son, and of the Holy Ghost to taught people. It is to be administered upon the confession that Jesus Christ is the Son of God. And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
Water baptism is for the remission of sins.
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. Baptism puts one into Christ. For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptized into Christ have put on Christ. Which is his body, the fullness of him that filleth all in all.
