The catechism provides Christians with three essential things to know in order to live and die in comfort: 1) How great their sins and misery are in order to understand their need for salvation; 2) How they are delivered from all their sins and misery through God's grace; 3) How they are to be thankful to God for such deliverance through their grateful response. It structures these three teachings around the concepts of man's guilt, God's grace, and the believer's gratitude, mirroring the structure of the book of Romans. The catechism uses the word "faithful" to describe Jesus' character, emphasizing his trustworthiness in both saving and keeping all those who belong to him.
