Kerby Anderson from Probe Ministries is a fellow with sharp insight into the Bible AND how the Bible relates to current culture. Probe Ministries itself is a terrific apologetics think-tank with dozens of articles geared to answer questions from non-Christians and to help Christians better interact with their society. I urge you to check it out and put it on your Bookmark list like I have in order to utilize it often.
I'd also encourage you to check out Kerby Anderson's latest book, Christian Ethics in Plain Language. And for an additional recommendation, here's Rebecca Hagelin's Town Hall column with a neat review of the book.
The order page for Christian Ethics in Plain Language on Amazon. com is right here -- and it's being offered at a very nice discount. Great reading for summer.
