What is True Faith?

The Heidelberg Catechism: Lord's Day 7

20. Questions: Are all men, then, saved by Christ just as they perished through
Adam?

Answer: No. Only those are saved who by a true faith are grafted into Christ and accept all His benefits.[1]

[1] Matt. 7:14; John 1:12; 3:16, 18, 36; Rom. 11:16-21.

21. Question: What is true faith?

Answer: True faith is a sure knowledge whereby I accept as true all that God has revealed to us in His Word.[1] At the same time it is a firm confidence[2] that not only to others, but also to me,[3] God has granted forgiveness of sins, everlasting righteousness, and salvation,[4] out of mere grace, only for the sake of Christ's merits.[5] This faith the Holy Spirit works in my heart by the gospel.[6]

Answer: All that is promised us in the gospel, [1] which the articles of our catholic and undoubted Christian faith teach us in a summary.
