Love Wins: A Book About Heaven, Hell, and the Fate of Every Person Who Ever Lived

Few notes on condemnation for those who hope that God will provide eternal pains for sinners:
Matt 10:28 "Do not fear those who kill the body but cannot kill the soul; rather fear him who can destroy both soul and body in hell." - notice that "he" in the hell destroys both body and the soul, nothing is left over.

Jude 7 "Likewise, Sodom and Gomorrah and the surrounding cities, which, in the same manner as they, indulged in sexual immorality and pursued unnatural lust, serve as an example by undergoing a punishment of eternal fire." Where is that fire today? Do we try to dream about some invisible fire in other dimension, or fire did what it did and their punishment's consequences are eternal?
Notice also Mal 4:1-3 when God speaks about final punishment and salvation, what happens is one group has eternal life, the other have eternal punishment, where nothing is left of them:

Mal. 4:1 See, the day is coming, burning like an oven, when all the arrogant and all evildoers will be stubble; the day that comes shall burn them up, says the LORD of hosts, so that it will leave them neither root nor branch. 2 But for you who revere my name the sun of righteousness shall rise, with healing in its wings. You shall go out leaping like calves from the stall. 3 And you shall tread down the wicked, for they will be ashes under the soles of your feet, on the day when I act, says the LORD of hosts.

I think you have to understand that eternal life and eternal death are two opposites, not the two parallel lives in the age to come. It started in Eden when God warned first humans about the possibility of death if they disobey God's commandment, and that was opposite to eternal life. But it was serpent who promised "You will not surely die". Since that time humans try to believe that death is not death but still another life in another realm.

We just cannot accept simple Bible truth. Death is the last enemy, Bible says, which will be destroyed (Rev. 20:14 Then death and Hades were thrown into the lake of fire. The lake of fire is the second death.) If even death is destroyed in the end, where are all those who chose death? Gone with the wind which blows away ashes... (Mal. 4).

So many things in theology depend on which verses you choose or want to see, and which ones you ignore. If you take these verses into account, then Bell is quite right in his conclusion.
