And behold, a lawyer stood up to put him to the test, saying, “Teacher, what shall I do to inherit eternal life?” He said to him, “What is written in the Law? How do you read it?” And he answered, “You shall love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind, and your neighbor as yourself.” And he said to him, “You have answered correctly; do this, and you will live.”
(Luke 10:25-28 ESV)
Let the principle contained in these words, be one of the foundation principles of our Christianity. Let the Bible, the whole Bible, and nothing but the Bible, be the rule of our faith and practice. Holding this principle we travel upon the king’s highway. The road may sometimes seem narrow, and our faith may be severely tried, but we shall not be allowed greatly to err. Departing from this principle we enter on a pathless wilderness. There is no telling what we may be led to believe or do. Forever let us bear this in mind. Here let us cast anchor. Here let us abide.
It matters nothing who says a thing in religion, whether an ancient father, or a modern Bishop, or a learned divine. Is it in the Bible? Can it be proved by the Bible? If not, it is not to be believed. It matters nothing how beautiful and clever sermons or religious books may appear. Are they in the smallest degree contrary to Scripture? If they are, they are rubbish and poison, and guides of no value. What says the Scripture? This is the only rule, and measure, and gauge of religious truth. “To the law and to the testimony,” says Isaiah, “if they speak not according to this word, it is because there is no light in them.” (Isaiah 8:20.)
