If you are seeking in-depth, thorough treatments of the toughest questions thrown at the Christian faith, Glenn Miller's A Christian Thinktank is the place for you on the web.
I believe Miller expresses this best when he writes:
"It would be easy to attack the 'fortress' of the Christian case on many, many small-medium points, BUT TO CONSTRUCT AN ALTERNATIVE SYSTEM that would be able to withstand the same caliber of intellectual examination on as many fronts, I put well beyond the practical realm of feasibility.
Thirty+ years of questioning and study and increasing honesty with the data (good, bad, and ugly) later, I have a worldview that has been confirmed in so many ways--intellectual, experiential, spiritual. I have so MANY MORE UNANSWERED QUESTIONS NOW than I did then, but I have had SO MANY "Tough Ones" answered already, that I have a "justified belief" that my core worldview (although very corrigible) is nonetheless basically on track.
There is no complacency herein...I still agonize over some issues, and 'fret' about others and analyze scores more...but I have learned that it is the God of Truth himself who drives me into the questions and who 'stokes the fire' in my pursuit of truth." 
Miller explains elsewhere the primary purpose of his ministry:"I try to help people find answers to tough questions that shred their souls."
