initial reaction miracles

Miracles often serve dual functions in religions: (i) they typically meet an immediate need (healing, feeding people, parting seas for escape, etc.) and (ii) they give credibility to the claims of the person who performs the miracle. Hume is interested in the credibility function of miracles. He notes that the claims of the Christian Bible (the holy book of the dominant religion of his time and area) and the authority of the Christian Church rely on the testimony of miracles.He comes up with a very interesting argument against belief in reports of miracles. He doesn’t say they can’t or don’t happen, he just says those who hear the report of a miracle always have a good reason for rejecting the report.How do you think Hume’s argument might go? Why do you think he argues we should not typically believe the report of miracles?
