Hi Kat
God is just but not cruel. - It would be cruel of God to drag people out of hell and put them into heaven, becasue they hate God so much. It would also mean that God would be taking away a persons freedom to choose between God or self.
a god so cruel as to burn people for all eternity. - Hell is the absence of God. People choose it, God does not send them there.
He wants to eradicate sin from the universe - He wants lovers who freely choose him (reject sin) rather than robots forced to worship him.
I couldn't enjoy heaven knowing there was such a corner, especially if I knew some of my loved ones were there. How could the tears be wiped from my eyes knowing this? If they were gone and not suffering any more, it would be different. - Great questions which I have no answer for. One of the mysteries of God I suppose.
Now what about that question I asked you.
If this is true then what do these verses mean?
Matt 25:41
