On Universalism...

One very effective argument to universalism is that of the double payment. If we agree that God is a just God, then he cannot require double payment for sin, i.e., if Christ died on the cross for all men and those who die in their sins spend eternity in hell as puishment for them, then sin is paid for twice. Our God is a just God and does not require this. Hence we see that the Lord died for his elect and not all men. Augustus Toplady portrayed this in one of his hymns when he wrote:

Payment God cannot twice demand

First from my bleeding surety's hand

And then again from mine
