Randy Alcorn answers a call-in question on Along the Way radio show. Oct 2009.

Universalism originated in the Garden of Eden when Satan said ‘you will not surely die’ (Gen. 3:4). The appeal by Universalists to God’s desire to save all is unconvincing because the same God who reveals that He desires for everyone to be saved also reveals that not everyone is saved. Additionally, we must distinguish between God’s sovereign will (which God infallibly brings to pass in the world), and His permissive will (what He does not want in and of itself, but wills to occur in light of all of history considered together).
