But further, Christianity itself, in all its full-orbed light, may be embraced as a system of religious belief. A person may be intellectually delighted--almost entranced with the glorious doctrines of grace, a full, free gospel, salvation without works, justification by faith; in short, all that goes to make up our glorious New Testament Christianity. A person may profess to believe and delight in this; he may even become a powerful writer in defence of Christian doctrine, an earnest eloquent preacher of the gospel. All this may be true, and yet the man be wholly unconverted, dead in trespasses and sins, hardened, deceived and destroyed by his very familiarity with the precious truths of the gospel--truths that have never gone beyond the region of his understanding--never reached his conscience, never touched his heart, never converted his soul. This is about the most appalling case of all. Nothing can be more awful, more terrible, than the case of a man professing to believe and delight in, yea, actually preaching the gospel of God, and teaching all the grand characteristic truths of Christianity, and yet wholly unconverted, unsaved, and on his way to an eternity of ineffable misery--misery which must needs be intensified to the very highest degree, by the remembrance of the fact that he once professed to believe, and actually undertook to preach the most glorious tidings that ever fell on mortal ears. O! reader, whoever thou art, do, we entreat of thee, give thy fixed attention to these things. Rest not, for one hour, until thou art assured of thy genuine, unmistakable conversion to God. PART III.
