H2Andy:
i guess my question is:
can there be moral lives without God in them?
I don't think we can solve this by asking non-believers to formulate scriptural arguments, or by asking Christians to accept that their beliefs may not be universally true. What I think we can do is examine the question, and try to derive an answer from it.
The question is, "Can there be moral lives without God in them?"
If not, and assuming a moral life is an objectively verifyable thing, it should necessarily be possible to tell if someone has God in their life by the way they live it. If it is moral, they do. Otherwise, they may not.
Of course, arriving at a mutually acceptable definition of morality might be necessary for arriving at a consensus. If morality is defined exclusively as "acting in accordance with God's will", then that morality cannot exist without having God in one's life. If, however, a more general definition, such as "motivation based on ideas of right and wrong" is used, then yes... obviously you can have a sense of right and wrong based on any number of social, religious, experiential, or philosophical foundations which do not necessarily include God. The key point of contention may be whether or not you accept that a moral foundation different from your own can still be the basis for behavior that can be considered moral.
If I don't believe in your god, am I necessarily immoral? Am I amoral? Are my morals somehow less valid than your religious morals if they still permit me to function in society, have a fulfilling life, and act as a positive influence on the lives of others? I may go to hell when I die for not caring what any supposed god thinks about me choosing to act the way I think a person should instead of choosing to act like I've been told a god wants me to, but since I don't actually believe in an afterlife of punishment or reward, I'm far more concerned about how my morals influence things in my current physical existance.
Is it not enough to strive toward making this existance better for all?
