Hume

In this book Hume says that we do not really have any reason why we should believe in miracles and that our evidence for the truth of the Christian religion is less than the evidence for the truth of our senses. He also says that we cannot be confident on others testimony because it is hearsay from that person's experiences. So therefore our knowledge of miracles only comes from the ones who claim to have witnessed miracles. I believe some of what he is saying because how can we really believe what someone tells us? How can we believe that it was a true miracle? However, for the people who really did witness one how can they prove it? So does that mean that you can only see it or experience it in order to believe it because if you haven't than there is too much doubt?
