Preaching is the assumption others want to hear about your religion. It’s a bit like being a Magic the Gathering Fan boy. You’re going to tell everyone about it even though their eyes are glazed over and they have tried to change the subject 3 times in the past 5 minutes. Live a life that makes people go, hey why are you so kind and generous and loving I want to know about that, then answer their questions, otherwise you’re just another boring fanboi prattling on.
