Why are you taking the word of people, when you yourself claim that it's God alone who judges people?
So basically you're saying that the Bible is mistaken... what is it, then, that convinces you of this, and that we are reincarnated after we die? I'm very curious to know where you're getting all this doctrine from, because in my experience it's unique to hear these kinds of views from someone who calls themselves a Christian.
I have no idea where you got this picture painting idea from, and what any of this has to do with painting a picture of God having ultimate power (are you saying that he doesn't?)
As Jack stated, the passage talks about salvation by grace, and not by works, which is contrary to what you were saying about taking steps towards heaven.
