We are told that in the Great White Throne Judgment, success will be measured in faithfulness and/or good works which have been performed through faith in Him. Those works based upon efforts independent of God, are parlayed into evil by the Adversary and will be judged for eternal merit as simply good for nothingness. They might be good for a few minutes, a few months, a few years, maybe a couple of centuries, but they pale in comparison to even the simplest good work performed through faith in Him, which will receive an eternal reward.
