Those that openly deny Christ and Jehovah God will not be given a second chance. However, those that are misinformed or were never shown the truth will be risen and given a second chance.
If only the believers were to be resurrected, then all of the starving tribesmen in Africa and elsewhere would be doomed to damnation and never given a chance.
The way I see it, I'm not denying Christ. He could very well be the truth, the light, ect... but there's just not enough proof right now to solidify my faith. I'm still seeking answers and I think that the Bible may have them. Again, I'm still learning.
