"If there is no God, then the future prospect for humanity is quite dismal. Based on the record of history, and those on here, it would be a continuing trouble-filled existence, or worse"
Quite the contrary, given all the trouble and strife that fanatical belief in the existence of different flavours of gods has given us over the centuries.
It is really quite shameful how you continually denigrate mankinds own efforts to improve the lot of our species, and focus solely on the negatives. Such relentless doom and gloom is the only way that fanatics can continue to justify their faith.
And the other cardinal error is to keep asserting, as a matter of truth, of fact, the existence of a god for which there is absolutely no compelling evidence at all.
People close their eyes to your "message" because, quite simply, you and your scriptural verse and biblical references have absolutely nothing positive to offer. No solutions, nothing useful. The childrens cartoon show, Spongebob Squarepants, contains more uplifting, inspirational and useful advice on life than all of your posts combined! :)
