The first and most basic question answered by the Confession is the question, For what are the Scriptures sufficient? The Confession makes clear that the Scriptures are not sufficient for every conceivable purpose in human life. They are sufficient for “all things necessary for his own glory, man’s salvation, faith and life.” The sufficiency of Scripture is vertical in nature. It has to do with our relationship to God. It tells the Christian how to glorify God, what he needs to do to be saved, what He must believe as a matter of Christian doctrine, and how he must live in order to please God. There is nothing that we need about those matters that are not in Scripture. Still, the Scriptures are not a math, biology, or Spanish textbook.
