Isaiah 51:7 Hearken unto me, ye that know righteousness, The people in whose heart is my law; Fear ye not the reproach of men, Neither be ye afraid of their revilings.
We that know Him and His righteousness are to listen to Him. He has saved us. He has made us righteous. He has changed our hearts. He has taught us His word. We are not to worry about what man can say or do. They may curse us and say all sorts of things about us but we know and love God.
