From Biblical Worldview Academy.
A story is told of an East Coast pastor who began his sermon with the statement all religious beliefs are true. During the sermon a college student near the front squirmed in his seat as he listened to the pastor preach. At the end of the sermon, as the congregation was filing out the back, the pastor greeted them. The student tried to sneak out but the pastor stopped him and asked him where he was from? He said I am on break from a seminary in Bowling Green. The pastor asked what religious belief he was and the student said he’d rather not say. The pastor asked why not? The student replied I don’t want to offend you. “Oh son,” the pastor replied, “it doesn’t matter what your beliefs are, they are all true. So what do you believe?” The student said okay and whispered in the pastor’s ear, “I believe you are going to hell.” The pastor got red faced and said, I guess I made a mistake. All religious beliefs cannot be true, because yours certainly isn’t true!
