...and yet it should be observed that Jesus died for them too.
They think that non-believers don’t die the second death but spend eternity with an unquenchable (eternal) body suffering in an unquenchable fire. And many of them refuse to even discuss it.
I don’t have that sort of vengeance regarding non-believers. They are all possible converts as far as I am concerned. And I also feel no ill will toward any of them. Rather, they have my pity. God reserves meeting out vengeance to Himself alone. I am to love my enemy.
This is very true; we Christians are not given the Judgement Seat in respect to men's souls (but may be given it in legal matters; jury-duty comes to mind) -- instead, Jesus told us to go out and make disciples of all men; furthermore, the mark that is to discriminate the believer from the non-believer is love.
John says that it is impossible to love the unseen God if we do not love the seen brothers, there is some extension to the non-believer if you are loving your Christian-brethren while loving God: God made man in His image, if you love God then why would you not-love those that bear His image?
