From my experience many people have problems with the doctrines of Grace at Limited Atonement and Irrestible Grace. When I was grappling with these issues a few years back, I too had problems with them. But I finally came to grips with them by understanding them this way... Atonement is both limited and unlimited. It is unlimited to all who will repent and believe. And yet it is limited to only those who repent and believe. Otherwise you have universalism. I have never liked the term Irresitble. I prefer to look at it as Inevitable Grace. Man can run and resist God at points, ie Jonah. But God's purpose of Grace will always be accomplished in God's way and God's time. Just some thoughts....any others?
