Jesus is unimpressed with words. He is unimpressed with those who merely come and listen. Rather, the mark of a fully devoted follower is one who comes, hears, but also does. Obedience is key. As Jesus finishes His famous Sermon on the Mount, He gives one final call for self-examination. He wants us to wrestle with the question of whether we are mere hearers, or also doers. For that is the distinguishing mark of a true disciple.
