Teach children about Jesus at a young age,

[Bob Kelso]

Clearly the people in the emboldened part weren't religious, or else why are they acting surprised when they are about to be let into heaven? Now this wouldn't be the case for those that heard the gospel and rejected it, it's for those that never had the opportunity to hear the gospel yet were good people. Hence the separation of the sheep from the goats; in other words the good from the bad.

*my bold*

We aren't talking about those that have never heard the gospel though, are we? The subject was indoctrination of young children, and my alternate point was that Christians don't teach their young or their congregations that you can enter heaven through good works alone. If you're one of the Christians that believes the unsaved who have never heard "the word", then that's fine. It's completely beside the point though. 

Moral of the story? Love everyone, that's the best lesson you can teach a child.

Hebrews 13
2 Do not forget to show hospitality to strangers, for by so doing some people have shown hospitality to angels without knowing it.

I don't necessarily disagree, with the addition of teaching your children the qualities of those undeserving of their love (abusive folk and their like).
