Calvinism Part 2 - The Unconfusing and Comprehendible

Okay, first of all I want to say want a Dummkopp I was earlier. I said I believe in the doctrines of grace...that's what Calvinists call their "Teachings of God's Sovereignty" Oops. I meant the other kind of doctrines of grace. Hehe. But, I was kind of mistaken in my last post. Where am I now?

I read some info on Calvinism today. It all makes sense, though a difficult realization. Except for one thing...

Continue to work out your salvation with fear and trembling.
Philippians 2:12

That's the only thing keeping me from excepting this theology. Everything makes sense except for this verse. It contradicts Calvinism. It makes it their salvation, our salvation. Huh? I though the salvation is God's to give us. Why would we need to work out salvation?

I think it very well could be truth...but why would God give even a hint of it not being truth?
I'll be praying about this more...
