Let’s say I were a Christian, but my kids were not. How could I possibly enjoy heaven with the knowledge that my children were burning in hell in endless suffering? I would resent God and wouldn’t want to be with him in heaven because of his lack of mercy. How could I want to stay in heaven? Or continue to love God? People just assume they will die and be with the ones they love because it makes them feel good – but this is not always the case according to Jesus or God.
I would rather suffer for eternity with my children than let them suffer alone while I live it up in heavenly bliss.
