These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power. II Thessalonians 1:9
There has always been much speculation about reward and punishment at the end of time. The Bible says there is reward for the faithful and punishment for those who don't know God and don't obey the gospel. We may think we can tolerate any punishment, but that is a foolish thought. Eternal punishment away from the presence of the Lord and the glory of His power is the worst of it all. We all bask in the presence of the Lord now and enjoy the benefits whether we believe or not. The future will be different. We can insure His presence later with the lives we live now.
