Know What You Believe

Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of Me. – John 5:39

The first thing in faith is knowledge. A man cannot believe what he does not know. That is a clear, self-evident axiom. If I have never heard of a thing in all my life, and do not know it, I cannot believe it. And yet there are some persons who have a faith like that of the fuller, who when he was asked what he believed, said, “I believe what the Church believes.” “What does the Church believe?” “The Church believes what I believe.” “And pray what do you and the Church believe?” “Why we both believe the same thing.” Now this man believed nothing, except that the Church was right, but in what he could not tell. It is idle for a man to say, “I am a believer,” and yet not to know what he believes; but yet I have seen some persons in this position…They believe they intend to go to chapel next Sunday; they intend to join that class of people; they intend to be very violent in their singing and very wonderful in their rant; therefore they believe they shall be saved; but what they believe they cannot tell. Now, I hold no man’s faith to be sure faith unless he knows what he believes. If he says, “I believe,” and does not know what he believes, how can that be true faith? The apostle has said, “How can they believe on Him of whom they have not heard? And how can they hear without a preacher? and how can they preach except they be sent?” We believe that every doctrine of God’s Word ought to be studied by men, and that their faith should lay hold of the whole matter of the Sacred Scriptures, and more especially upon all that part of Scripture which concerns the person of our all-blessed Redeemer. There must be some degree of knowledge before there can be faith. “Search the Scriptures,” then, “for in them ye think ye have eternal life, and they are they which testify of Christ;” and by searching and reading cometh knowledge, and by knowledge cometh faith, and through faith cometh salvation.~ C.H.
