This god that you are proclaiming seems to me to be some kind of cosmic monster; who purposes to predestinate certain people unto everlasting burnings without giving them a choice in the matter of whether they can repent and avoid that fate.
Watch the histrionics of language. Calvinists do not worship a different God, but the one true and living God. They accept and trust Him as He is, recognizing that He knows all things, and by comparison, we know next to nothing. He is infinite. We are finite. He is the Creator. We are the creature. If you would see HIm as a monster for choosing who shall live in His house and inherit His kingdom, what do you have to say about the things He instructed the Israelites to do to other nations?
Prov 16:4 The Lord has made everything for its purpose, even the wicked for the day of trouble.
God passes over those whom He does not elect unto salvation, and they are guilty of high crimes and treason against their Creator. So there is a sense in which they are predestined to this but the two predestinations are not completely parallel. Both are unconditional in the sense (to clarify what I said earlier to
@Bob Carabbio) that those elected to salvation are not elected because they are better than others and those He passes over, He does not do so because they are worse than others. The parallelism departs here. Those elect unto salvation do not deserve their redemption. The reprobate do deserve their fate. They get what they earned. The elect get what they did not earn--- grace. But we all come from the same lump of clay.
The Bible tells us these things and to say it isn't true because it interferes with our idea of God and who He would or should be, how we want Him to be, is to simply vainly shake our fist at Him. Redemption is for us, but it is not about us. It is about God and His glory.
When we believe that we are saved because of something we did, it opens the door to trusting in our actions as our eternal security, and all too often get not much farther than looking at us, and stop looking to God and seeking His face, that we might partake daily of the bread of life, and drink deeply of the living water, seeking Him, to learn of Him.
