If you are interested in undesigned coincidences, head on over to Answering Muslims and check out the work of Jonathan McLatchie. McLatchie has a lot of good material on a lot of subjects and is generally a very smart and interesting writer. He has posts on Old Testament UCs here, here, and here that I have not covered.
In other news, my book Hidden in Plain View is right now ranked #1 new release on Amazon in the category of Jesus, the Gospels, and Acts. I was interviewed today by Eric Metaxas and will let readers know when that interview will air. I thought it went well.
