I'm in a Calvinism mood right now (whatever that is).
This Theopedia article on Calvinism is excellent, as is Theopedia itself in general I am sure. Also, check out this page on John Piper stuff at Monergism.com. And finally, don't miss this Spurgeon gem, "A Defense of Calvinism."
So, if you're not a Calvinist, you should be. I can't promise you that you'll be happier, but I can almost guarantee that I will like you more as a result. :) (Of course, please understand this is not a fellowship breaker between Christians, or at least should not be). Though I am completely convinced that Calvinism is true, Christianity is far larger than Calvinism by itself (a subset at best), and greater still is our Lord Jesus Christ, the author and finisher of our faith of Christianity.
