This is baloney. If one doesn't know Christ, then one has to be sinless. One either must lead a perfect life according to the law, or one must be saved thru faith in Christ. Nowhere in scripture is another plan outlined. Grace only comes through Christ - no other plan available. This is more apostasy. "Strive by their deeds..." - here we go again with earning salvation! Let me ask you something: Is there such a thing as a person who has not broken the 10 commandments? Question #2: Can sin be forgiven other than thru the blood of Christ? Question 3: Can a perfectly just an Holy God NOT punish unwashed sin? The pygmies in Africa who do not know Christ are not going to hell for not hearing the gospel, they are going for breaking God's laws! Period. Nevertheless, everyone will get a fair deal.
Maybe not. Let's see...
For all men were by nature foolish who were in ignorance of God, and who from the good things seen did not succeed in knowing HIM WHO IS, and from studying the works did not discern the Artisan.
But either fire, or wind, or the swift air, or the circuit of the stars, or the mighty water, or the luminaries of heaven, the governors of the world, they considered gods. Now if out of joy in their beauty they thought them gods, let them know how far more excellent is the Lord than these; for the original Source of beauty fashioned them. Or if they were struck by their might and energy, let them from these things realize how much more powerful is He who made them.
For from the greatness and the beauty of created things their original Author, by analogy, is seen. But yet, for these the blame is less; For they indeed have gone astray perhaps, though they seek God and wish to find Him. For they search busily among His works, but are distracted by what they see, because the things seen are fair. But again, not even these are pardonable. For if they so far succeeded in knowledge that they could speculate about the world, how did they not more quickly find its LORD?
