Bill O'Reilly says he got the inspiration to write "Killing Jesus" in the middle of the night.
According to Mr. O, since he is a Catholic, that means the Holy Spirit urged him to write the book. Right away, we have a theological problem. Based on my understanding of Scripture, a person is not filled with the Holy Spirit because they are a Catholic. They are filled with the Holy Spirit because they are a Christian. Bill seems to get those two confused quite often.
