I guess you could say Jesus was the first Christian, since he was the Christ.
And as the first Christian, Jesus spoke more about hell that any other biblical figure. But, he is also the figure that said that he didn't come to condemn the world, but to save it.
So with verses like these:
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels - Mt. 25 :31
And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell. Mt. 10: 28
What are we to think? What did the first believers think on this topic? Yes, it is a hard teaching. One, that most Christians wouldn't mind if it wasn't part of Christianity. But, if you believe that Jesus resurrected himself from the dead like he predicted that he would, why would we doubt anything he said??
Would it be "in character" for Jesus to allow people to believe something false for 1800 years until a man who believed he was named in scripture as "that faithful servant" appointed over all of humanity (C T Russell), was born and corrected Jesus by announcing that hell was actually cold, & not hot?
What say you?
