Deep in our hearts, many of us Christians do not believe the damnation of Hell.
I remember watching a film on the holocaust of the Second World War. To exterminate the Jews quickly, they were herd into the gas chamber a few hundred at a time. The door was closed, and the Jews died inside. Death was relatively quick, perhaps in minutes or hours. Their cries of pain and anguish could not even be heard, because all the German guards left the place after the gas was turned on.
That scene could not be erased from my mind.
Jesus Christ is not like that. On the Judgement Day, He will not condemn millions and billions of people to the eternal fire of Hell. He will not close the door of Hell and let anyone suffer eternally inside. Our God is a God of Love, Lovingkindness and Mercy. He may chastise and punish us for our sins, but the punishment will not be eternal Hell.
So if you were told Christians go to Heaven, and non-Christians go to Hell, think again. It is impossible for God to use Hell to inflict eternal punishment on any of His own creation. Jesus will forgive 70 x 7 times, or even 700 x 7 times.
That is the confidence of knowing the character of God. The wonderous love of Jesus Christ.
