My Heart Hurts!

I have a good friend who believes herself to be a Christian. But she happened to come over while another friend and I were having a discussion about the Bible, and she basically looked at us like we were daft and scoffed at us for believing in the virgin birth and other miracles. I defended my faith in the Word and let her know my stand, but was too flabbergasted and heart broken to do much more. I am praying that the Lord gives me more opportunities to talk to her about this. She noted that her pastor is a procaimed agnostic and doesn't belive in such miracles as well. I didn't know that was even possible! I have some studying to do to prepare for my talks with her...and then wait for the Lord's opportunity.
