It is through that Grace alone that we are saved, through faith alone. We don't earn our salvation through our works. And all our works are equally condemned because sin taints them all. If you think you've earned salvation because of what you do or do not do, or what you believe or do not believe, you are quite simply an ungrateful fool.
I wouldn't go so far as to condemn your repudiation of Christ's sacrifice as blasphemy because quite frankly, I couldn't care less what you think or believe. God will save you or not, regardless of how incorrect and unBiblical your theology. And thanks be to God for that!
That's it, and that's all. The multiple volumes of dense theology all boil down to these two simple paragraphs.
