That is a good question and not easy to answer.When there is conflict in which what some one claims Jesus told them it wouldn't be Jesus causing the conflict.We have seen lots of claims that haven't panned out.But, we can not dare to say that Jesus does not communicate and in several different ways.We really do need to seek him individually and deeplyIt is an awesome thing when Jesus does give us revelation of something ahead of time.So we can not discount warnings from him, but of course there is plenty of deception.So for us to understand if it is ligit or not we ourselves need that close relationship that does not exclude his unique ways of speaking to us.Faith is a strange thing, but that is what he requires.
