Here is a short list of websites that deal with Apologia or the study of Apologetic’s. I’ll add more as I come across them.
Alpha & Omega Ministries – Dr. James White is a very good resource.
Institute for Religious Research
Monergism – This is probably my most favorite website. It’s like going to WalMart in that it is “one stop” shopping. They have just about everything!
RZIM – The Webpage of Ravi Zacharias
Stand To Reason – Greg Koukl and staff are very good Christian Apologist’s.
Rated R For Reformed
