The objection to a soul with value existing in hell would seem to be based on the incorrect assumption that man can reject God, yet retain his intrinsic value.
I have noticed that some atheists are very indgnant about the issue of hell, and assert that God could have just created people who were going to be saved anyway, therefore negating the need for people going to hell. I note that this was tackled in a recent podcast, and Dr Craig notes that may not be feasible because people (even atheists) have a role to play in bringing people closer to salvation, challenging others, presenting counter arguments etc. The atheist may then introduce the idea of a philosophical zombie (convincing humanoid robot) who could do this work without the subject knowing, thus obviating the need for hell once again. This got me thinking about the false premise upon which the argument is based, ie, that the best possible world is one where no souls existed in hell. Although it seems counter intuitive, I don't think this is the same as saying that the best possible world is one in which all were saved (which would be true). Taking the idea of the Potter (I think Rom 9:21 and 2 Tim 20) making some vessels for honour and some for dishonor, it would make sense that the chamber pot only has value while it is in use within the home. At some point in time, it will be cast aside, and its value will be gone. A similar analogy would be that we don't like the fact that food has spoiled and needs throwing away, but we don't really grieve for it once it has been disposed of. It is terrible that it went bad, but of no consequence once it has been thrown away. It no longer has value. The objection to a soul with value existing in hell would seem to be based on the incorrect assumption that man can reject God, yet retain his intrinsic value. Clearly this touches on the apparent dichotomy between election and free will, but I'm willing to accept on that the two can work together in a world where God wills all to come to salvation, yet chooses the ones who do (that's a theological argument, and slightly off topic) . I would be interested to know your thoughts.
