Shouldn'T a Moralist Lead a Clean Life and Inspire

I have never preached morality, but followed strict and essential rules taught by mother to prevent a tragedy; aren't I happy to have listened to her words? Preachers mention eloquent quotes from the Gospels, and while preaching there's no proof of their honesty, only honest folks do not sin, lie or shout threats' he may have sinned and lied hiding his insincerity. Open the pages of the Bible and read them carefully, don't misread the holy words that offer guidance; shouldn't a moralist lead a clean life and inspire? Whoever thinks that they're vain is bound for calamity.
