Our Sole Authority

There is nothing more important in the Christian life than the way in which we approach the Bible, and the way in which we read it. It is our textbook, it is our only source, it is our only authority. We know nothing about God and about the Christian life in a true sense apart from the Bible. We can draw various deductions from nature by which we can arrive at a belief in a supreme Creator. But I think it is agreed by most Christians, and it has been traditional throughout the long history of the Church, that we have no authority save this Book. We cannot rely solely upon subjective experiences because there are evil spirits as well as good spirits; there are counterfeit experiences. Here, in the Bible, is our sole authority.
