I think it is un-Christian to wish or condemn others to hell. I see it all the time here in this forum and in my personal life.
Indeed, some people are practically gleeful about it. For example, some old lady I know will see somebody doing something she doesn't agree with and she will rub her hands and say something along the lines of "Well they are not going to be so happy when they are burning in hell. They are going to get theirs alright."
I see similar responses in a lot of threads here too.
Personally, I think it is unbecoming of Christians to presume that they are the judges of who will or will not go to hell. I say let God sort them out.
I have walked with Christ and Christians for 20 years.
Not once have I ever seen or heard any Christian express anything like joy or satisfaction that someone is on their way to Hell. Not once.
And no one is attempting to judge who will or who will not go to Hell. There is one Judge, and His word is final. All who reject Him will spend eternity in a lake of fire. He said so. To merely repeat what He has clearly stated is not condemning anyone to anything.
FWIW-I agree with you.
