I didn't have a choice but to lift you up. And sing whatever song you wanted me to.
-- U2, "Magnificient"
Theologically I'm not prepared to defend to death every minor point of Calvinist theology, but I've found recently the more of God's word I read, the more plainly I understand that our salvation is not our own doing. Sure, real Arminians also believe in prevenient grace, but I can't buy the idea that we have anything whatsoever to do with our eternal destination. (And for the record, I don't think Arminianism is a weak position; I simply think Calvinism carries more Biblical weight.)
For me, embracing Calvinism is embracing a paradigm-shifting thought: I'm not in control of jack squat. I can't will to do good. I can't give God a wink and a nod, saying, "Go ahead, do your stuff in me." And I certainly can't work out my own salvation with fear and trembling; it's got to be God working in me, and it is. I'm comforted knowing that what He starts He completes, and He'll perfect His work (both in me and my family) until the day of Christ JESUS (Philippians 1:6). I know that's true. I have no fear of losing salvation because it's not up to me to keep it. He will come through.
In the past I've dipped my toe into the waters of Calvinism, but I've never (I don't think) flat out said I was a Calvinist. I guess that's what I am. The theologically snooty part of me would rather be called a monergist or even an Augustinian, but Calvinist works just fine.

Wait a second... did you type this in wrong: "And I certainly can't work out my own salvation with fear and trembling;" ? Wouldn't that be in direct contradiction with Phillipians 2:12-13? Or that one of those weird Calvinist things that only makes sense to people that believe in it in the first place?
