Just thought I'd chime in for the heck of it.
I live and I die, that's all that really concerns me, and I do not fear death, I welcome it as a part of everyone's life. I am eternally grateful to have a life and when I die, I wouldn't have really lost anything, just gone back to what I was to begin with; nothing.
I mind my own business and do not concern myself over who believes and doesn't believe what, since it doesn't affect me in the slightest. I believe faith is an extremely powerful tool that can lead many people to live grand, fulfilling lives, putting spirit and hope in believers' eyes. People say religion starts war. Well, there is good and bad to everything in the world. Humanity tends to focus more on the bad caused because it is more interesting to discuss. Such as the news reporters', "If it bleeds, it leads."
Hollowshield, I can completely understand your confusion as to how such people can be happy and I can safely speak for myself in saying, I'm happy. I don't need a guide to help me through, and if there is one, I thank Him for his kindness towards a non-believer such as myself. But, in the end, it doesn't matter to me, I live my life as good as I can be, I live for others, and I live to make others' lives more bearable. I take great joy and pride in helping those in need and putting warm smiles on friends' faces.
I hope that little rambling shed some light on my particular viewpoint. If you have any further questions out of curiosity, do feel free to give me a shout.
