True Religion is Born From Knowledge of Truth

Benjamin Breckenridge Warfield on truth in religion:

"The grounds of religion must be taught and learned as truly as the grounds of anything else. Let us make no mistake here. Religion does not come of itself; it is always a matter of instruction. The emotions of the heart, in which many seem to think religion is too exclusively to consist, always follow the movements of thought. Passion for service cannot take the place of passion for truth, or safely outrun the acquisition of truth, for it is dreadfully possible to navigate sea and land to make one proselyte, and when he is made, to find we have made him only a "son of hell".

This is why God establishes and extends his Church by the ordinance of preaching; it is why we have Sunday schools and Bible classes. This is why God has grounded his church in revelation. He does not content Himself with sending His Spirit into the world to turn men to Him. He sends His Word into the world as well. Because it is from knowledge of the truth, and only from the knowledge of the truth, that under the quickening influence of the Spirit true religion can be born."
