Australian theologian Michael Bird has recently published a book on evangelical theology (excerpts of the book can be found here). This is how Bird describes Calvinism:
"When I explain Calvinism to people, I usually say this: “People suck, they suck in sin, they are suckness unto death. And the God who is rich in mercy takes the initiative to save people from the penalty, the power, and even the presence of this sin. This is Calvinism, the rest is commentary.” "
On that basis I am glad to be a Calvinist too. What about you?
