Does this apply to the millions of people that have never even heard of Jesus Christ? Give your brain a rest. It needs it.
Those who "have never even heard of Jesus Christ" have light like a weak flashlight. Those who hear the good news of Christ's death for sinners are like those standing in Madison Square Garden before a bank of Hi intensity lights. Men are not judged on HOW MUCH light they have, but WHAT THEY DO with the light they have.
The testimony of scripture and experience is that men universally turn away from the true God, and either worship themselves, their pleasures, or false religions.
THAT is what men are judged for (See Romans 1-2 for a more detailed explanation)
>>Does this apply to the millions of people that have never even heard of Jesus Christ?<<
Only if they've never worshipped other Gods, lied, stolen, coveted, murdered, dishonored their parents, committed adultery...
If God's plan is to save a tribe of Aborigines who have never heard of him, he will send a missionary.
If you're that concerned about those who have never heard of God, you ought to repent of your sins, dedicate your life to Christ, and serve him in the jungles, seeking the lost and preaching salvation to them.
Nope...But you tell us about it, o wise one...
