Hi. This si my first time posting here. I wasn't sure where to post this question so I hope it is ok here.

I have been a christian since I was 17 (in my late 20's now), but I am ashamed to say that I am not very well versed in the Bible or very good at explaining "WHY" I beleive what I do.

Last night some friends came over and we got talking about christianity and the beliefs that Christians hold. While there are many differing opinions throughout denominations I view my walk with God as one based on the Bible. My friends who are not yet saved but are very curious and searching kept asking questions escpecially pertaining to their favorite television show "Crossing Over with John Edwards" I voiced that while I cannot say for sure, I do not think this is of God nor glorifying to his cause. I got blasted with questions like what is the difference between a phycic and a prophet and how do you know the difference, and how can you say that he (john Edwards) is not bringing messages of peace from God through peoples passed family members. While I have read of sorcery and stuff in the bible, how can I relate this to them (my friends) in a more modern sense. My very long and emotional conversation with them last night left me confused and angry that I couldn't better defend my faith. Any thoughts? Reading I could do? Anything?

Thanks,

Julie
