The gospel, according to Isaiah, is, “Incline your ear, and come unto Me: hear, and your soul shall live.” It is ours, then, to give men something worth their hearing; in fact, to instruct them. We are sent to evangelize, or to preach the gospel to every creature; and that is not done unless we teach them the great truths of revelation. The gospel is good news. To listen to some preachers, you would imagine that the gospel was a pinch of sacred snuff to make them wake up, or a bottle of ardent spirits to excite their brains. It is nothing of the kind; it is news, there is information in it, there is instruction in it concerning matters which men need to know, and statements in it calculated to bless those who hear it. It is not a magical incantation, or a charm, whose force consists in a collection of sounds; it is a revelation of facts and truths which require knowledge and belief.
The gospel is a reasonable system, and it appeals to men’s understanding; it is a matter for thought and consideration, and it appeals to the conscience and the reflecting powers. Hence, if we do not teach men something, we may shout, “Believe! Believe! Believe!” but what are they to believe? Each exhortation requires a corresponding instruction, or it will mean nothing. “Escape!” From what? This requires for its answer the doctrine of the punishment of sin. “Fly!” But whither? Then must you preach Christ, and His wounds; yea, and the clear doctrine of atonement by sacrifice. “Repent!” Of what? Here you must answer such questions as, What is sin? What is the evil of sin? What are the consequences of sin ? “Be converted!” But what is it to be converted? By what power can we be converted? What from? What to? The field of instruction is wide if men are to be made to know the truth which saves. “That the soul be without knowledge, it is not good,” and it is ours as the Lord’s instruments to make men so to know the truth that they may believe it, and feel its power. We are not to try and save men in the dark, but in the power of the Holy Ghost we are to seek to turn them from darkness to light.
