And so, 2. We would know, that many a man may believe, and yet not know that he doth believe. He may set to his seal, that God is true in his offer of life through Jesus, and accept of that offer as a truth, and close with it; and yet live under darkness and doubtings of his faith, long and many a day; partly through not discerning the true nature of faith; partly through the great sense and feeling of his own corruption and unbelief; partly through a mistake of the Spirit's operations within, or the want of a clear and distinct uptaking of the motions of his own soul; partly because he findeth so much doubting and fear, as if there could be no faith where there was doubting or fear, contrary to Mark ix. 24. Matth. viii. 26, and xiv. 31.; partly, because he hath not that persuasion that others have had, as if there were not various degrees of faith, as there is of other graces, and the like. Therefore, 3. We would know, that many may really believe, and yet miss this sensible sealing of the Spirit which they would be at. God may think it not yet seasonable to grant them that, lest they forget themselves and become too proud; and to train them up more to the life of faith, whereby he may be glorified; and for other holy ends, he may suspend the giving of this for a time. 4. Yet we would know, that all that believe, have the seal within them, 1 John v. 10, "He that believeth on the Son of God, hath the witness in himself," that is, he hath that which really is a seal, though he see it not, nor perceive it not; even the work of God's Spirit in his soul, inclining and determining him unto the accepting of this bargain, and to a liking of and endeavouring after holiness; and the whole gospel clearing up what faith is, is a seal and confirmation of the business. So that the matter is sealed, and confirmed by the word, though the soul want those sensible breathings of the Spirit, shedding abroad his love in the heart, and filling the soul with a full assurance, by hushing all doubts and fears to the door; yea, though they should be a stranger unto the Spirit's witnessing thus with their spirits, that they are the children of God, and clearing up distinctly the real work of grace within their soul, and so saying in effect, that they have in truth believed. But enough of this; seeing all this, and much more is abundantly held forth and explained, in that excellent and useful treatise of Mr. Guthrie's, entitled, "The Christian's Great Interest."
