How many people will be declared righteous by performing religious acts? Zero. How many mouths will be able to give an excuse for their behavior? Zero. How many of us will be held accountable to God? All of us. So with this truth, Jesus moves on to address the true nature of sin and righteousness and it has nothing to do with the way you wash your hands or whether you eat catfish or not.
