It is possible […] that you have been looking for salvation in the mere belief of a certain creed. You have thought that if you could discover pure orthodoxy, and could then consign your soul into its mould, you would be a saved man; and you have consequently believed unreservedly, as far as you have been able to do so, the set of truths which have been handed to you by the tradition of your ancestors. It may be that your creed is Calvanistic, it is possible that it is Arminian, it may be Protestant, it may be Romish, it may be truth, it may be a lie; but, believe me, solid peace with God is not to be found through the mere reception of any creed, however true or scriptural. Mere head-notion is not the road to heaven. “Ye must be born again” means a good deal more than you must believe certain dogmas. It is of the utmost possible importance, I grant you, that you should search the Scriptures, for in them you think you have eternal life; but recollect how our Lord upbraided the Pharisees. He told them that they searched the Scriptures, but he added, “Ye will not come to me that ye might have life” (John 5:40). You stop short at the Scriptures, and therefore short of eternal life. The study of these, good as it is, cannot save you; you must press beyond this—you must come to the living, personal Christ, once crucified, but now living to plead at the right hand of God, or else your acceptance of the soundest creed cannot effect the salvation of your soul. You may be misled in some other manner; some other mistaken way of seeking peace may have beguiled you, and if so, I earnestly pray that you may see the mistake.
You must understand that there is only one door to salvation, and that is Christ; there is one way, and that is Christ; one truth, and that is Christ; one life, and that is Christ. Salvation lies in Jesus only; it does not lie in you, in your doings, or your feelings, or your knowings, or your resolutions. In him all life and light for the sons of men are stored up by the mercy of God the Father. This may be one reason why you have not found the light; because you have sought it in the wrong place.
