D&C 75:22

Why will it be more tolerable for the heathen than for those who reject the missionaries? Elder James E. Talmage noted that "man will be accounted blameless or guilty, according to his deeds as interpreted in the light of the law under which he is required to live." It is inconsistent with our conception of a just god, to believe him capable of inflicting condemnation upon any one for noncompliance with a requirement of which the person had no knowledge.
