Again, all are free to accept the spiritual leadership of Mr. Calvin, but it's because of his arguments with Scripture that some freely choose to reject him and his teachings and accept Jesus and his instead.
Did Jesus have no foreknowledge, and when does he in fact possess that? He says, "Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity." Calvinism's private translation, the ESV, says "you workers of lawlessness".
Look it up, the etymology of the word "iniquity" is to be uneven, inequal. Yet Calvin accuses God of being lawless?
John Calvin: "But I had good reason for saying that two steps are here to be observed; for in the election of the whole nation, God had already shown that in the exercise of his mere liberality he was under no law but was free, so that he was by no means to be restricted to an equal division of grace, its very inequality proving it to be gratuitous." (Institutes, Ch 21, Of the eternal election, by which God has predestinated some to salvation, and others to destruction.)
The Bible speaks of the man of lawlessness.... Believers believe that was not Jesus. For Mr. Calvin to declare that God is not equal with men doesn't make it true, but is the very thing God accused Israel of doing: "Yet ye say, The way of the Lord is not equal. Hear now, O house of Israel; Is not my way equal? are not your ways unequal? Ezek 18:25
Calvinist's are not Israel are they? It appears that Israel hadn't learned anything from the righteous Law of God, nor accepted it as indeed righteous:
"And judgment is turned away backward, and justice standeth afar off: for truth is fallen in the street, and equity cannot enter. Yea, truth faileth; and he that departeth from evil maketh himself a prey: and the LORD saw it, and it displeased him that there was no judgment. Isa 59:14,15
This goes to the very heart of the controversy over Calvinism, why men reject Mr. Calvin's thoughts and ways, which, as the Calvinist above admits, are not Gods. And it seems to be why Calvinism is unable to answer "how" Jesus judges people to heaven or hell. No judgment of men before their decree of eternal destiny can be found in Calvin's system. But is that true? What does Jesus say about his judgment of men? Did Jesus not give us a Standard by which he judges men to be believers or unbelievers?
Again, "how" does Jesus judge people? (Hint: He says, as I hear I judge...." in John 5:30. When and What does he hear, and with what does he compare what men say that enables him to justly judge men to be believers or unbelievers? (Is it true, as Calvin says, that it is nothing in men that provokes the just judgment of Jesus? Or rather, could it be that Jesus hears the truth some men tell about God and the lies other men tell about the same God?)
