here are twenty-five presentations in the book, "Last Call? (Subtitled: A Christian Challenge to Atheists, Agnostics, & Skeptics!)." All except five, are updated and/or revised versions of one or more presentations in the original version of the "Last call?", with the subtitle: "(Are You Really Serving God?)." At five hundred forty-four pages, the original version was too large (about the size of a ream of typing paper) and too heavy. Most of the feedback, which we received, indicated that too many readers thought that the original version read like a (college) doctoral thesis. The author and the editor did their best to correct both the size issue and the readability issue via the "Last Call? (Subtitled: A Christian Challenge to Atheists, Agnostics, & Skeptics!)."
