The sufficiency of Scripture So doctrine comes from authoritative sources, the first of which is Scripture. And beginning with Moses and all the Prophets, he explained to them what was said in all the Scriptures concerning himself. The Gospels add to the already-sufficient testimony of the Old Testament. Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
Scripture is sufficient to direct our spiritual growth.
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work. Therefore, any teaching which goes beyond what Scripture says must not only be regarded as less authoritative, but also nonessential. Summary We should look first to Scripture to determine our beliefs and actions.
