Simone R. (who writes this lovely and personal little blog) gave me this good bit of advice the other day that I'm benefitting from. This is my recollection anyways, so don't (a) blame Simone for poor sentence construction or (b) get confused by the quotation marks.
"When I was going through my questioning time at college I decided that I had to have an anchor. I made my anchor the Bible. Everything and anything else could be wrong. Everyone else in the world could be wrong. The whole of history of the church could have got this thing wrong. But I decided that the Bible must be right. And it was very freeing."
I think that was about it. A good tip.
