The measure of this knowledge. It is impossible to determine with precision just how much knowledge is absolutely required in saving faith. If saving faith is the acceptance of Christ as He is offered in the gospel, the question naturally arises, How much of the gospel must a man know, in order to be saved? Or, to put it in the words of Dr. Machen: "What, to put it badly, are the minimum doctrinal requirements, in order that a man be a Christian?" In general it may be said that it must be sufficient to give believers some idea of the object of faith. All true saving faith must contain at least a minimum of knowledge, not so much of the divine revelation as of the Mediator and His gracious operations. The more real knowledge one has of the truths of redemption, the richer and fuller one's faith will be, if all other things are equal. Naturally one who accepts Christ by a true faith, will also be ready and willing to accept God's testimony as a whole. It is of the utmost importance, especially in our day, that the churches should see to it that their members have a fairly good, and not merely a hazy, understanding of the truth. Particularly in this undogmatic age, they should be far more diligent than they are in the indoctrination of their youth.
