For the past few centuries the largest organized religion on the planet has been Christianity, which made it an easy target for philosophical salvos from skeptics, nihilists and atheists alike. 
Unfortunately during that time, a lot of apologetics writing (a branch of theology dedicated to proving and defending Christianity) has been dominated by dusty language and tomes; circular logic and unimpassioned writers.
The luminary exceptions can be counted on two hands including such noted authors as C.S. Lewis, William Lane Craig, Richard Swineburn and Alvin Plantinga.
You can add to that short list of outstanding apologetic writers, Ravi Zacharias.
