(Excerpt from the post "The Character of God")
I have had many conversations with agnostics and atheists alike. The one argument they never fail to bring up is this idea of forever torment in hell for those who decide not to believe in God. Way back when, before I studied the subject thoroughly in the Bible, I would do my best to defend the doctrine and water it down like everyone does these days. I would say, "Well, God doesn't send anyone to hell - they choose to go there themselves." You know, those kind of cop-out statements.
"At its core, hell is about being in a wrong relationship to the Source of all Love, Goodness and Life... As the writer of Hebrews puts it, "Our God is a consuming fire". We can be warmed and comforted, or we can be scorched and burned."
"...Your enemies...Your foes... You will burn them up as in a blazing furnace. The LORD will swallow them up in His wrath, and His fire will consume them..." - Psalm 21:8-9
"His winnowing fork is in His hand, and He will thoroughly clear His threshing floor; and He will gather His wheat into the barn, but He will burn up the chaff with unquenchable fire." - Matt. 3:12, Luke 3:17 (remember that 'unquenchable' means that no one can put out or resist the fire, it does not mean that the chaff will be burning forever.)
"If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned." - Jesus (John 15:6)
"... a certain fearful expectation of judgment and a fury of fire that will consume God's enemies." - Hebrews 10:27
I would venture that even the atheists could recognize the justice of the Owner cleaning His own house.
