God isn't a thing, person or entity. You will die, and that will be it. No heaven, no hell, you will simply cease to exist. And all the individuals you're casting damnation upon will be perfectly fine, not a single thing will happen to them as a result of being homosexual, being immoral in your eyes or anything else you have a problem with for that matter. You and your evangelism do not matter in the slightest, you will wither away and fade into nothingness.
