I believe that, at this present time, we are in great danger of being burdened with a crowd of so-called converts who do not really know anything as it ought to be known. They attended a revival meeting, were much excited, and thought they were converted; but just ask them to explain to you the simplest truths of the gospel, and you will soon discover how little they know. Could they explain the three R’s, ruin, redemption, and regeneration Do they know what the ruin is? Do they know what the remedy for that ruin is? Do they understand at all what it means to be born again? Do they comprehend what the new nature is, or what “justification by faith” means. Perhaps someone says, “They do not comprehend your theological terms.” I do not mind whether they know the meaning of the terms that are familiar to many of us; but do they know the truths themselves? There is a certain degree of Christian knowledge which is absolutely necessary to salvation.
Charles H. Spurgeon (1834 – 1892)
