God does not condemn us to hell; God wishes all humans to be saved. He will love us to all eternity, but there will exist the possibility that we do not accept the love and do not respond to it. And the refusal to accept love, the refusal to respond to it, that precisely is the meaning of hell. Hell is not a place where God puts us; it is a place where we put ourselves. The doors of hell, insofar as they have locks, have locks on the inside.
