There is little I have less tolerance for than the person who claims they know you are wrong because God told them so. How might you respond to such a person? Let me illustrate one method in the form of a dialogue:

David: That’s not what that verse means.
Jason: Why do you disagree with my interpretation?
David: The Holy Spirit revealed to me that it means X.
Jason: That’s funny. The Holy Spirit revealed to me that it means Y.
David: No he didn’t. The Spirit cannot contradict Himself, and I know He told me it means X.
Jason: I agree with you that the Spirit cannot contradict Himself. And since I know He told me it means Y, He could not have told you it means X.
David: You’re wrong.
Jason: Ah, wait. The Spirit is speaking to me right now. … Oh, ok God. David, the Holy Spirit just told me that He did not tell you that it means X.
David: No, He didn’t tell you that.
Jason: Yes, He did.
David: No, He didn’t.
Jason: Yes, He did.
David: No, He didn’t.
Jason: Yes, He did.

Silly, I know. The reason it is silly, however, is that it is silly to claim the Spirit told you X, when you cannot justify X. Anyone can appeal to the Spirit as their intellectual justification, but that does not mean they actually heard from the Spirit, and it does not help to persuade anyone else of their view (even if they really did hear from the Spirit). It stifles the conversation, and persuades no one.

Furthermore, what do you do when two people think God told them something, and yet He said something different to each person? The dialogue ends in a stand-still in which each person accuses the other of not truly hearing from God. Not very fruitful, if you ask me.
