xiv, 22, the Apostle says, ‘Hast thou faith? have it to thyself before God.’ The scope of his reasoning shows that nothing is there meant by faith, but a conviction of the truth in regard to the article of which he had been treating, namely, the equality of days and meats, in point of sanctity, under the Gospel dispensation. The same is evidently the meaning of the word, verse 23, ‘Whatsoever is not of faith, is sin;’ where, without regard to the morality of an action abstractly considered, that is concluded to be sin which is done by one who doubts of its lawfulness. 2. As to spiritual gifts, prophecy and inspiration in particular, they appear to have been accompanied with such a faith or conviction that they came from the Spirit, as left no room for hesitation. And indeed it is easy to perceive that something of this kind was absolutely necessary to enable the inspired person to distinguish what proceeded from the Spirit of God, from what was the creature of his own imagination. The prophets of God were not acted upon like machines in delivering their predictions, as the diviners were supposed to be among the Heathen, but had then, as at other times, the free use of their faculties, both of body and mind.” This caution is therefore with great propriety given them by the Apostle, to induce them to be attentive in prophesying, not to exceed the precise measure allowed them, (for different measures of the same gift were committed to different persons,) and not to mingle aught of their own with the things of God’s Spirit. Let him prophesy according to the proportion in which he has received this gift, which is in proportion to his faith. Though a sense somewhat different has been given to the words by some ancient Greek expositors, none of them seems to have formed a conception of that sense, which, as was observed above, has been given by some moderns. This has, nevertheless, a sound and sober principle included in it, although capable of great abuse. Undoubtedly there is a class of great and leading truths in the Scriptures so clearly revealed as to afford principles of interpretation in doubtful passages, and these are so obvious that persons of sound minds and hearts will not need those formal rules for the application of the analogy of faith to interpretation, which have been drawn up by several writers, and which when not misleading, are generally superfluous.
