When you ask an Arminian friend if it would just if God left us all in our sin and saved no one, most answer yes, we are sinners and justly deserve God's wrath. But then turn around and ask, if God decided to pardon a number of these ill deserving sinners, but gave over the others to the justice they deserve, these same people suddenly cry out "that makes God unfair". Yet how can the former be okay in their eyes, but not the later? Does not God have the right to do what He wants with His grace? And are not those rebels getting their just deserts? If He were somehow obligated to give it to all, it would no longer be grace now would it?

Remember we indiscriminately cast the seed of the gospel to all people. God is holding no one back from believing. Their rejection of Christ and His gospel is completely willful and voluntary. They will not have Christ rule over them. Yet God still has mercy on many such rebels, giving them eyes to see, ears to hear and a new heart to believe.
