Members of those other religions think the exact same thing about your religion.I know I'm going to get chewed for this but, none of those religions were right. There is only one way to Heaven and the Bible tells you.
None of them make any sense to me as truthful. They are all clearly belief in fantasy, similar to belief in Santa Claus but more complex. What you're asking is the same as shutting down our brains at Christmas and believing in Santa. You can't force people to believe something which isn't true.See which one makes more sense to you.
You have to trick them. For example, telling us that going to church won't hurt a bit, but if we don't go, we will burn in hell for eternity. So you know, that line of reasoning will get you chewed out. Not because it worries people, but because you're expressing a negative sentiment towards others.
