"Kingdom of God"

A question was asked in religion class today;

What are your perceptions of "The Kingdom of God"?

Many believers often perceive that as the eternal life in heaven in one's afterlife. The ticket to its entrance is known to be a "good person"/live a "good life", as well as being faithful to one's religion, jesus christ, god, holy spirit, etc.

Funny, the teachings say not to expect anything in return for doing good, yet they believe in the existence of "Heaven".

... Well, is that not different to asking for something in return for doing good?

Perhaps I lack background information, but excluding whatever that may be, this is one of the many contradictions in christianity, or maybe even religion itself.

Another thought; already mentioned to a few friends, but nevertheless.
I think there are more religiously faithful kids in public schools than in private. This is something that needs clearing.
After 6 years of attending a private(catholic) school, you do not get "brainwashed" or "converted".
Sure, they make you pray very often, make the sign of the cross, recite prayers, sing hymns and worship their god - or at least pretend to be listening - but the catholics don't force you to believe what they believe. It's not some.. interrogative institution.

Oh by the way, we don't get funds from the government, it all comes from the ridiculous school fees and students' fundraising.

Private schools are just schools that arn't run by governments, but run by religious followers/leaders, period.

In fact, I speculate that there are more believers in public schools than in private. To be honest, I don't think anyone at all, in my year group, attends sunday masses, recite the rosary or even pray before meals.

So no, not all us private school kids arn't all god-worshipping-goodie-goodies.
Many of my peers would laugh at the idea of attending church.
But yes, some do attend church. Although I'm pretty sure it's for social purposes more than anything, really.
