Then death and Hades were thrown into the lake of fire. The lake of fire is the second death.
Hell is the place or state we choose apart from God’s grace in Christ. It is beyond my comprehension, and I really don’t want to dwell on it. But it is sobering. We get what we chose in this life in the end maybe so to speak, in spades. We either choose the light God gives us, or recede back more and more into the darkness, our own as well as that of this world.
I don’t see it as a physical lake of fire, but as something that is tormenting us more and more, as we live life apart from God.
Whether or not hell is forever (I think from the Bible it is, but you can make a case that it might be temporary either in annihilation at a certain point, or actual purification, though I think myself the latter is more far fetched), and I hope not myself, people receive what they deserve.
I like C.S. Lewis’s view of it as something we choose for ourselves in this life carried on into the next life. Humans were made for relationship with God and with each other. But sin separates us from God and from others. So in the eternal state we keep moving further and further on the track we chose in this life.
It is hell to live apart from God on our own. If we make our own light or depend on another light other than that of the gospel, then we’re indeed in for great deception. Jesus said that if the light in us is darkness, then that darkness is great.
Hell is living apart from God and God’s good will. Even as Christians we can live in a kind of hell when we seek to live life on our own, or unwittingly give into either self-deception or satanic deception. That’s a far cry from living in God’s grace in Christ in which we trust and obey and depend on God to see us through.
It’s a big subject, just a few scattered thoughts here. God grant us to rest in Christ. God took hell for us in himself at the cross, so that we never have to experience a shred of it here (though we still do at least from time to time), and none in the life to come. In and through Jesus.
