Chapter 25 — Lord's Day 25

Section 67. Q. 67: Are both the word and the sacraments then intended to focus our faith on the sacrifice of Jesus Christ on the cross as the only ground of our salvation? A. Right! In the gospel the Holy Spirit teaches us and through the holy sacraments he assures us that our entire salvation rests on Christ's one sacrifice for us on the cross.
