It is always easier to deal with the sin “out there” in the world than it is to deal with the evil “inside here.” The sins of others are easy to see, label, and offer suggestions for overcoming.
The difficulty of faith is to address the issues inside of our hearts.
Before you try to change someone else, take a long look in the mirror. The world needs fewer people trying to coach others into righteousness and more people trying to be righteous themselves.
Start making adjustments with the person in the mirror. That should keep you busy for a while.
