Scripture Readings: Romans 6:1-7; 1 Peter 3:18-22; Acts 2:38-39; Matthew 28:18-20

Question 69. How does baptism remind you and assure you that Christ's one sacrifice on the cross is for you personally?
Answer. 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.

Question 70. What does it mean to be washed with the blood and Spirit of Christ?
Answer. It means to have forgiveness of sins from God, through grace, for the sake of Christ's blood which is shed for us in his sacrifice on the cross, and also to be renewed by the Holy Spirit and sanctified as members of Christ, so that we may more and more die unto sin and live in a consecrated and blameless way.

Question 71. Where does Christ promise that we are washed with his blood and Spirit as surely as we are washed with the water of baptism?
Answer. In the institution of baptism where he says: "Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit." "The one who believes and is baptized will be saved; but the one who does not believe will be condemned." This promise is repeated when Scripture calls baptism the water of rebirth and the washing away of sins.

For study and discussion:
