It seems there are many authors that preach books and there are many that write them. Do you see advantages and drawbacks to both approaches? David Jeremiah and Erwin Lutzer seem to preach allot of their books. Ray Comfort writes his books and the style and writing excellence shows right up when doing it this way. Personally I think it is better to write books, but not everyone agrees with me. Some preachers plagiarize, do not cite their sources and such all because they preach their books.
