Dispensational truth has supposedly provided a hermeneutical key to unlock prophetic interpretive mysteries in a literal way. It is interesting that dispensational truth had its beginning in the early nineteenth century along with a number of other heresies. Since the turn of the century dispensationalism has far exceeded the Jehovah's Witnesses in false prophetic predictions. There is no denying that these predictions cause great emotional excitement among dispensationalists. This writer, formerly a dispensationalist was oftentimes thrilled hearing about the predictions of the pre-tribulation rapture that was to take place in 1981. In reality, the excitement or thrill experienced when gaining a dispensational understanding of prophecy is more reminiscent of Gnosticism's concealed or secret knowledge (only possessed by those initiated into the deeper mysteries or dispensation truth) than a correct knowledge of the Bible. Those who live in glass houses should not cast stones, lest their own house shatters.
