What sustains me is the knowledge that I am doing God's will by witnessing to the truth which leads to our salvation. I find the fact that many try to deny this truth in spite of the abundant evidence shown by their own abilities quite upsetting.
Where is this "abundant evidence"? Why haven't you posted even a hint of it?
Perhaps you should ask your god to actually give you the first hint of a morsel of a shred of a scintilla of
actual evidence or reasoning to support your absurd and self-contradictory claims, instead of just endlessly repeating baseless assertions, blind faith, total gibberish, and many basic mistakes in reasoning (fallacies). At the moment you are just making you and your faith look dishonest, stupid, and stubbornly ignorant.
If your god is too busy thinking up the next natural disaster or nasty disease to visit on humanity, perhaps you could do
yourself some favours and actually attempt to learn something about logic and think about and properly respond to the replies you are getting, instead of endlessly regurgitating the same, tired old script.
