The Bible does NOT support Calvinism.
I believe that it does. Lots of Calvinists and Reformed folk believe the same. I do not think that it is a matter of salvation. Most Calvinists, I believe, would hold the same view. Probably why most of us do not spend a lot of time destining those who hold other views to hell.
The word "Predestination" only appears in the Bible 4 times.
I will take your word for it. Easy to check, not worth the effort. But, so what? You have as a pet doctrine the "Re-imputation of Sin." That term is found how many times in Scripture? The concept is found how many times in Scripture? To the best of my knowledge, the answer to both questions is zero. Feel to correct me if I am incorrect, but if your argument against Calvinism hinges at all on the number of occurrences of the term, then for the sake of intellectual honesty, it had better be greater than four.
No where is the word, "predestination" related to anyone being predestinated.
There is no scripture about anyone being predestinated to heaven or to hell.
Different term, but same meaning, I believe: Acts 13:48 speaks to the issue...

You want to grab a handful of scriptures and make a doctrine out of them.
I believe that the Reformed system has the best overall explanation of the total teaching of Scripture. Yes there are hard parts and verses. But that would be true of any theological system.
At any rate, grabbing a handful of scriptures and making a doctrine out of them is a lot more sound than take a handful of no Scriptures and making a doctrine out of one's vain imagination, see above regarding the Re-imputation of Sin Doctrine.
You are desperate to believe a lie so that you don't have to accept Jesus Christ as your only means of salvation.
Calvinists and Reformed folk accept that Jesus Christ is the only means of our salvation.
