Q. 75 How does baptism remind you and assure you that Christ’s one sacrifice on the cross is for you personally?
A. In this way: Christ instituted this outward washing and with it gave the promise that, as surely as water washes away the dirt from the body, so certainly his blood and his Spirit wash away my soul’s impurity, in other words, all my sins.
Matt. 3:11; Rom. 6:3-10; 1 Pet. 3:21
Q. 76 What does it mean to be washed with Christ’s blood and Spirit?
A. To be washed with Christ’s blood means that God, by grace, has forgiven my sins because of Christ’s blood poured out for me in his sacrifice on the cross. To be washed with Christ’s Spirit means that the Holy Spirit has renewed me and set me apart to be a member of Christ so that more and more I become dead to sin and increasingly live a holy and blameless life.
Zech. 13:1; Eph. 1:7-8; Heb. 12:24; 1 Pet. 1:2; Rev. 1:5
Ezek. 36:25-27; John 3:5-8; Rom. 6:4; 1 Cor. 6:11; Col. 2:11-12
Q. 77 Where does Christ promise that we are washed with his blood and Spirit as surely as we are washed with the water of baptism?
A. In the institution of baptism where he says: “Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” “Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.” This promise is repeated when Scripture calls baptism the washing of rebirth3 and the washing away of sins.
