I am quite surprised...some truly thought-provoking answers.
SolidlyHere--You seem to be a doubting Thomas in the closet.
You say, "I don't know if I consider the Bible as a source of my morality.I look at it as a source of Faith.
Faith helps me look at Life as a Game. If I play it well, I get a good Afterlife".
Quite poetic indeed, but it seems the Bible does in fact mandate that you follow its moral guidelines in order to, as you put it, win the game.
Second, you stated that you were uncertain if God was in your heart. I'm assuming by God in your heart you mean the "Holy Spirit". The Bible is quite clear that doubting the Holy spirit is the only unforgiveable sin. (See Luke 12:10)
I am Glad, of course, that you do not interpret the Bible literally, but the problem with your viewpoint is that it is both logically and theologically consistent.
Elman--The creation argument in all of it's varying forms is invariably weak. First, you say that it is more reasonable--and therefore, more simplistic--to believe that you were created. According to this light, all things in existence must have a creator. But, using your logic, the creator must have a creator, and that creator also must have creator, etc. The creation argument extends itself ad infitum, and therefore makes the problem infinitely more complex; it is scarcely a solution. If you argue that the creator has always existed, then why can't the chemical processes that bring about life have always existed? Furthermore, there are plenty of examples of unintelligent design: still born children, children with deformities, mental retardation etc. Was God just simply drunk at the wheel when he created these poor souls? Third, even if the creation argument were true it would not indicate that the Bible (or for that matter any other religous text or creed) is true; all it would indicate is that there is a creator. Zeus, Allah, Aliens, etc. could all be the creator.
I very much agree with your assesment of Human nature: "we are all born with unless we are morrally or mentally defective, that good is loving others and bad is hurting others." However, I do not agree that the Bible confirms that assesment in anyway. First, The doctrine of original sin states that we are all born evil sinners and that we can only be moral by following the ethics prescribed in the Bible. Second, the Bible does not define morality in terms of human suffering as you or I do. According to the Bible all people of other religions should be killed, rape victims should be killed, anyone who violates the 10 commandements should be killed, slavery is perfectly o.k. as long as you don't injure your slaves teeth and eyes when you decide to beat them, etc.
