The are and practice of selling one's credibility for future delivery.

Don't ever prophesy; for if you prophesy wrong, nobody will forget it; and if you prophesy right, nobody will remember it.

Fear prophets and those prepared to die for the truth, for as a rule they make many others die with them, often before them, at times instead of them.

Prophecy today is hardly the romantic business that it used to be. The old tools of the trade, like the sword, the hair shirt, and the long fast in the wilderness, have given way to more contemporary, mundane instruments of doom --the book, the picket and the petition, the sit-in at City Hall.

There is no question but that if Jesus Christ, or a great prophet from another religion, were to come back today, he would find it virtually impossible to convince anyone of his credentials despite the fact that the vast evangelical machine on American television is predicated on His imminent return among us sinners.
