But do you hate God if Calvin was basically right about sin and grace?
Calvin imagined himself to be right about God. What he ventured to create shows that it was John Calvin that hated God.
Unfortunately, he didn't keep his ideas to himself and now there are a whole bunch of John Calvin like people believing in Calvin's god.
The purpose of John Calvin being born as I see it is to show people that anyone can make anything of the bible and its message. The can come up with a doctrine using the bible, they can twist those passages they choose and make all sorts of claims and stipulations about what it means to get right with God according to their creative inventing.
That doesn't mean that is what Jesus was about.
Before I was a married man I dated quite a bit. One young woman I was interested in was a Calvinist. I immersed myself in her church for over a year and all while I was a Christian that did not ascribe to Calvinism.
Quite the experience.
Later I met the woman I'd marry. She happened to own a flower shop that also had a bridge into landscaping by appointment. Our yard is spectacular. But to this day when I look at the layered tulip bed as it blossoms so beautifully beside the waterfall that flows in the background without chuckling just a little.
My wife always said I should let it go. And I assure her that I did but it still makes me laugh that a woman I knew so well, or thought I did back in the day, was so committed to a man's invention. And not only did he corrupt the words of God but he had to smear the image of a lovely flower for all time in the process. That batturd! haha. My wife still gets the joke.
