Well I don't post much but this seemed like a real interesting topic. A disclaimer first: I consider myself a progressive Christian in a historically anti-progressive branch of Christianity. My personal belief is that religion is merely an institution of man and that it is faith which is the true measure of one's relationship with God. I do not believe religion to be a bad thing, but I think that it is separate from faith in that you can have one without the other. I do believe that you need both faith in God and to attempt to live a good moral life to reach Heaven. In response to Playaa's post, no one can be good all of the time this is true. However, I think each individual person deep down will know if the life they have lived so far has been good or not. You cannot look for objective answers for a subjective question in response to Playaa's question. Unfortunately, I can only tell you what I feel is good or bad, and that is what I try to live my life by. There are not standards that you or I can judge another person's life and say this person is going to heaven or hell. For example, according to Christianity's teaching anyone can end up in heaven, even the most heinous of individuals, if they truly reconcile their sins and accept God. I cannot accept the idea that you cannot get into Heaven if you do not practice a religion, which is made by man. I do not think that God (Christian, Jewish, or Islam etc) is that petty. I think that faith and attempting to live a "good" life are the best ways to get to Heaven. I think the original poster is having issues of faith, believing that there is a God. That would be the real issue that I think the poster should address with himself. Since none of us know for sure, this only my personal view on this topic but maybe it will be helpful to someone somewhere.
P.S. - I am not anti-religion but many people mis-interpret it that I am when I make the argument of religion vs. faith (I follow a religion myself for example). Hopefully I have not offended anyone. [Those that KNOW they are going Heaven are the ones that probably won't get there.]
