The following tidbit from Carl McColman pretty much sums up the way I have thought about the whole eternal reward/punishment thing for years and years. It’s in the book, too: see if there is any divergence between the following comment and, say, John 3:19-21.
It’s impossible to be separated from God. Hell is not about being separated from God, it’s about choosing to resist the fire of Divine Love. Then, instead of making us incandescent, it burns. Integral consciousness recognizes that the key to heaven and hell lies within our heart. We are all predestined to spend eternity immersed in the presence of God, bearing the beams of God’s love. How we experience those beams — as heavy and burdensome, or as joyous as light — is, thanks to the free gift of grace, pretty much left up to us.
