Ric shared with me an inspirational link that I wanted to share with you. If you are thinking of quitting work, sprituality, perhaps life itself, this may help you. It is a very gentle message about the grace of God done in such a way as to be accessable to even the most cynical viewer.
I include it on the PBGs Path because its core message speaks to the PBGs big Plan. We may not know the part we play on God's stage, but there are no unimportant parts. In the big scheme of things, everything matters.
EDIT: I have never been close to suicide, so I don't really know if this message is helpful for that. If a google search brought you here, take a look. Perhaps it will give you the strength to carry on.
