Building off last week’s encounter with the Jewish religious leaders Jesus uses this as a teachable moment with crowds and the disciples. To show them that clean hands are not as important as a clean heart, and what goes into a person’s mouth according to Levitical Law is not what defiles them, but what comes out of their mouth makes them unclean. Jesus would agree with his half -brother James, that warns us against the dangers of a dirty mouth and the damage it can do, (10) from the same mouth come blessing and cursing. My brothers, these things ought not to be so. (11) Does a spring pour forth from the same opening both fresh and salt water? (12) Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water (Jas. 3:10-12 ESV). Going deeper in his diagnosis of our sinful nature, Christ gives Peter a lesson on the anatomy of our souls explaining to him that the mouth is connected to the heart, which is the fountain of our thoughts and actions. We must ask ourselves the penetrating question if the Great Physician examined us how would he describe our hearts?
