Hell is a place that is totally devoid of God and His attributes (love, peace, joy, happiness, etc.) and was originally created for Satan and...
his angels. When God backs the dumptruck and unloads sin into the burning trash dump of hell those who reject God and cling to their sin go there too....
Remember that the same God that sends people to hell also died for them. Does this sound reasonable to you?
If the person asks where's the proof for God/Jesus/Christianity, go here.
