Okay, how's this: The Salvific Will of God is not "universal" in the sense of a God who is desperately trying to save everyone, and yet often failing in His forlorn attempts.
The Commandment of God which attends to Salvation is universal in the sense that God commands all Men everywhere to Repent. THAT is universal.
This is not the same as saying that all Men will Repent. In fact, were it not for God's merciful Regenerating Grace unto His chosen, then none would obey the Universal command to Repent.
I think I have heard that every time I have embarked on this discussion with a Calvinist. There is a subtle but important distinction between being drawn to God and being drawn by God.
Do you believe that God can passively will anything? That is, do you believe that He can command people to repent and they won't repent? (Obviously you do since that was your citation of a universal salvific position.) Or perhaps you believe that He is commanding them to repent and at the same time, not?
God can will something passively. That is, He will be disappointed if all don't repent, don't you think?
