Morality versus afterlife

[Angrboda]

This is a question for anyone who thinks morality "comes from God".

If you knew there was no afterlife, that you're dead and gone no matter what happens in this life, would you continue to follow "morality from God"? Or would you then ignore it, and decide for yourself how to act?

Thanks

God's Law is Righteousness, Man's 'want to do' version of God's Righteousness is 'morality.'

Keeping in mind that man's 'morality' changes from culture to culture and from generation to generation. does not make what pop culture defines as 'morality' moral or right for a lack of a better term. it is simply 'right' for those in the majority..

That said without an absolute like God's standard of righteousness what keep society grounded in any sense of right and wrong? for instance what keeps a more advanced society from pushing a more primitive culture off it's lands and drives those people off the edge of extinction? Kinda like what America did with it's Indians? Or what Germany did with it's Jews? or what the world does with unborn babies it does not want.. Without some form of God's Righteousness pushing us to act in all instances, their wouldn't be Indians in America any more, Jews in Europe, or any restrictions on abortion.

So given the two choices of living under evil incarnate/man's morality and God's righteousness I choose God's righteousness and system of redemption, eternal life or not.

So a moral standard that is fixed and doesn't change is superior to one that does? In what sense?
