Everyone wants to hear directly from God. Everyone wants the comfort of having a message from the all-powerful creator of the universe. The good news is that God’s words have been preserved for you. God has committed His words “wholly into writing.”
“The Holy Scripture is the only sufficient, certain, and infallible rule of all saving knowledge, faith, and obedience…” The 1689 Confession of Faith opens with this unambiguous declaration that Scripture is the only sufficient standard of truth. All things pertaining to the Christian faith are found in the canon of Scripture. No where else. The modern world has no objective standard or rule by which to live. Everyone defines their own truth, decides who they are and want to be, and have completely abandoned the idea that there is a God who defines morality and reality. In contrast to this fallen worldview, the 1689 confession summarizes clearly and concisely what Scripture teaches about itself:
The Holy Scripture is the only sufficient, certain, and infallible rule of all saving knowledge, faith, and obedience, although the light of nature, and the works of creation and providence do so far manifest the goodness, wisdom, and power of God, as to leave men inexcusable; yet are they not sufficient to give that knowledge of God and his will which is necessary unto salvation. Therefore it pleased the Lord at sundry times and in divers manners to reveal himself, and to declare that his will unto his church; and afterward for the better preserving and propagating of the truth, and for the more sure establishment and comfort of the church against the corruption of the flesh, and the malice of Satan, and of the world, to commit the same wholly unto writing; which maketh the Holy Scriptures to be most necessary, those former ways of God’s revealing his will unto his people being now ceased.

Two Sources of Revelation…One Sufficient for Salvation
Notice first that the authors of the confession call out two ways God communicates who He is to humans: the Scripture and the “works of creation and providence.” In doing so, the authors are keeping with Psalm 19 and Romans 1 where the Bible says that God has revealed part of His glory and character through creation. When humans look out at the world around them, they should be able to deduce that there is a powerful, wise, and good ultimate Being who created the universe.
However, the authors are careful to distinguish between Scripture and natural revelation. The former they explicitly say is sufficient, while the latter is explicitly called out as not sufficient. In both cases, the sufficiency in view is “sufficient for salvation.” In other words, Scripture is the only sufficient standard in which you can find how to be reconciled to God. Natural revelation at the best only reveals that there is a God and He must have certain attributes.
Now, what does “sufficient” mean? It means that Scripture has in itself everything you need to be saved from your sins. It exhaustively contains the doctrines needed for being reconciled to God and then living in obedience to Him after you are reconciled. In using the word “sufficient”, the authors are making it clear that the canon of Scripture is all you need for salvation. You don’t need any supplementary or external material in order to understand and believe the Gospel. Not only that, Scripture is the sufficient standard for how Christians are to live in the world.
