Why it seems more logical:
1. If Calvinism were true, I dont think that I would want to go to Heaven, considering it would not sound very loving. All it would be is a place with some sociopathic God who created most people with no purpose except to be in some horrible place, not to mention the only saved people would have to be awful selfish. Personally speaking, in order to be a calvinist and okay with that teaching, you would have to be pretty selfish. So hell would sound a lot more loving and way less selfish.
2. If Arminianism were true, then that would not make God very powerful. If we were powerful enough to resist Gods will, we would also be powerful enough to turn hell into a utopian society. People have done it before without Organized Religion.
3. Once Saved Always Saved-according to the popular creed, it means that once one is saved, they are no longer capable of sin, or a free pass to sin. Televangelists like Pat Robertson who ask people to send him money to pray for the souls in Haiti is actually part of Gods will because PR is "Saved". In another instance, "Once saved always saved" gives you a freepass to sin. No payment for all the autrocities I am going to commit, no need to reform, because Im right with the Lord. But every non-saved is going to face unending wrath for not being born again. That sounds like some pretty messed up justice based on the "all or nothing" philosophy.
4. Faith Alone-preached in many Catholic and Protestant churches today. I have faith in Jesus, but I sin all the time, but that dont matter, im saved. Those who were not Christians are screwed eternally just for not being in the right religion.
5. If Heaven were exclusive only to the self proclaimed born again Christians, then heaven would be one dull place. The Born again Christian life is way too many rules, and pretty much sees anything fun as a sin.
6. Mortal Sin-According to Catholic theology, if one commits mortal sin, which pretty much is every single little sin. So according to that form of theology, you are at the beach one day, and see some girls in bikinis, and you have a dirty thought. A wave comes from the ocean and kills you. You go to hell. Why? because you just happened to have committed the sin at the wrong time, and never went through the priest. Too bad so sad.
7. Universalism-based on the principal that God has the full power and love to save everyone, but the catch is there is going to be chastisement for everyone based on their sins. No more no less. A hindu maybe required to leave behind any faulty beliefs and learn about Jesus, while a Hardcore fundamentalist may have the most trouble, having to learn to love their enemies, and humble themselves big time.
8. Its the only form of Christianity that seems exactly consistent with the bible. All the other Christian beliefs all require you to (a.) Ignore all scriptures that speak of universal Salvation and (b.) ignore all scriptures that contradict your beliefs. It is the only Christian belief system that can tie Mercy and Judgment together with Love. None of that Justice and Love are two separate things. It reduces all biblical complications, and is the only belief system that accepts the scriptures without needing to twist other scriptures.
