1 What shall we say then? Shall we continue in sin that grace may abound? 2 Certainly not! How shall we who died to sin live any longer in it? 3 Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? 4 Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

Q. 94. What is baptism?
A. Baptism is a sacrament, wherein the washing with water in the name of the Father, and of the Son, and of the Holy Ghost, doth signify and seal our ingrafting into Christ, and partaking of the benefits of the covenant of grace, and our engagement to be the Lord’s.
Question 69.—How is it signified and sealed unto thee in holy baptism that thou hast part in the one sacrifice of Christ on the Cross?
Answer.—Thus: that Christ has appointed this outward washing with water, and has joined therewith this promise that I am washed with His blood and Spirit from the pollution of my soul, that is, from all my sins, as certainly as I am washed outwardly with water, whereby commonly the filthiness of the body is taken away.
