Agape (selfless, sacrificial, unconditional love) is used in relation to God.
I understand that the concept of love has changed, just as our concept of god has changed...but wouldn't you say god, him/her/itself, hasn't changed? Just like our concept of the world has changed, but the world itself hasn't changed?
But, unconditional love would seem that no matter how bad the kid is, he'll always be loved and welcomed. He may not get candy, but he'll always be welcome.
One child breaks the rules and one doesn't; then one child suffers the consequences and the other receives the "prize". The idea that everyone gets candy no matter how they behave isn't an incentive to behave.
But candy is a temporary prize, and punishment is a temporary anti-prize. A punishment that last for eternity is not a punishment, or at least, is not a just punishment.
I guess its "unconditional" and "eternal" that are giving me issues. I can totally understand punishment and "prizes," but both would be as a way to condition someone, and as such, would have to be less than eternal.
