I could not defend it as a sign for unbelievers. If I do it publicly, men of all conflicting doctrines do the same. The Scriptures neither imply nor promise the continuance of the gift, but, in fact, states that they will cease while faith, and hope yet abide. For we know in part, and we prophesy in part. But when that which is perfect is come, then that which is in part shall be done away.
History records that the gifts did cease.
History records when and how the gift was supposedly revived. History records the deceitfulness of the modern day movement to increase the supposed gift among churches. He once did it, and therefore, He is doing it. It is setting believer against believer. The only unity it promotes is unity of men of a thousand different conflicting doctrines agreeing to disagree.
