1- If Calvinism is true, whomever God provides “irresistible grace” to will go to heaven and not suffer eternal hell.
2- If God is omnibenevolent, He would not desire to, nor would He, send anyone to suffer eternal hell for choices they were powerless to make without God’s irresistible grace.
3- If God is omnipotent, he could provide irresistible grace to all people.
4- If God is omniscient, he would know how to provide irresistible grace to all people.
5- Some people suffer eternal hell.
6- Therefore, either God is not omnibenevolent, or not omnipotent, or not omniscient (pick at least one), or irresistible grace (and Calvinism) is false.
