To the next question: responding to the Bible being fairy tales.
Though there is evidence to substantiate many statements/claims in the Bible, certainly there is not evidence for all. We take a lot on faith.
For myself, there is enough evidence that it makes the rest credible. So IF I come to believe that the Bible is my guide to life and God’s word, then I will get the most out of it if I take by faith what even seems to be incredible and unknowable. Over time, study, and experience and definitely the help of the Holy Spirit my faith has solidified in many ways, including a full belief in the Bible as the word of God. Do I understand ever word? No. Do I think every word should be taken literally? No. Do I think it accurately describes events that seem impossible (e.g. the feeding of the 5000)? Yes. But I probably did not get there overnight.
When people make negative statements about the Bible a good question is to find out just how much of it they’ve read? What to they know about the Bible? What kind of a book is it? Who wrote it? Are they responding to a cultural bias against the Bible and are ignorant? Or, have they really examined it and found it wanting? Do they believe that supernatural things are possible at all? Do they believe in the possibility of a creator? So many places to start a discussion.
Putting myself in their position, I’m sure I hold pretty negative views of the Koran. I’ve never read it. I know little of it’s history. Even so I would dispute it’s veracity and power to guide the life of individuals. I’m not so different from a person suggesting that the Bible stories are fairy tales. I believe if I had an expansive glimpse into the Muslim worldview I would still reject it. Perhaps this person feels the same way about Christianity.
I also think we have to understand that we live in a world where we cannot believe what we read. There is so much opinion on every side being represented as fact. It’s actually pretty incredible under those circumstances that we can believe the Bible to be the inspired word of God.
All this and I haven’t really said much, especially about how I would respond. I guess a lot would depend on my relationship with the person and how much I know about them and certainly how much I’m willing to invest in them personally. (I think we have to ask ourselves the honest questions if we’re going to do the same with someone else.) If I’m willing to invest myself in that person (and hopefully I am), I would invite them on a journey to see what’s really in the Bible and use the experience, if they are willing, to build a trusting and respectful relationship.
