don't see anyone saying these things but you.If Calvinism is consistent, then if God unchangeably determines every thought, motive, and deed, then you can't just give him credit for the good things. He may decree them in different ways. He has a secondary means for ways for one thing and for another he decrees it differently. But he's still unchangeably decreeing all of it. And there is no human power for any human being to do anything differently. And by the way, that would include Adam. And so, that makes him the author of sin. Because even the first evil intention, even the one in Satan's heart, Satan had no control. He had to do it. He had to want to do it. Whatever it is, you have to be consistent. I think Calvinists are inconsistent here. If you're going to give God the credit for all the good things, you have to give him the credit for all the bad things. and saying he's the author of sin, that makes him evil.
I wonder if you have a big nose
