Stand to Reason – An apologetics ministry led by Greg Koukl and his team. The website has a number of articles on a wide variety of issues, great podcasts and an online store with some wonderful books, DVDs, etc. The podcasts are great for people who aren’t into reading books.
Unbelievable? – A podcast by Premier Christian Radio and hosted by Justin Brierley; features moderated debate/discussion between many of the top experts (both Christian and non-Christian) on a wide variety of issues. Some of the subjects can be difficult to understand but you can pick and choose which podcasts you listen to.
Reasonable Faith – A ministry led by Dr. William Lane Craig who is, arguably, the top Christian apologist in the world today. His website features two great podcasts (including his Sunday school class which teaches systematic theology from an apologetics perspective), many great articles (both scholarly and lay level), and more. If you want to watch some excellent debates just type his name into YouTube. Be aware though, that some of the stuff that Dr. Craig puts out is quite advanced and more suitable for those who want to get past the basics.
Creation, Evolution and Intelligent Design - There are three main views that Christians take on this issue which are listed below. The fourth view (Intelligent Design) is an umbrella view encompassing both the Young Earth and Old Earth views.
