Jesus replied, "You, too? Are you being willfully stupid? Don’t you
know that anything that is swallowed works its way through the
intestines and is finally defecated? But what comes out of the mouth
gets its start in the heart. It’s from the heart that we vomit up evil
arguments, murders, adulteries, fornications, thefts, lies, and
cussing. That’s what pollutes. Eating or not eating certain foods,
washing or not washing your hands—that’s neither here nor there." Matthew 15:16-20 (TM)
The religious leaders of Jesus day were great at passing judgment and pontificating on things that were easy to see. Did he wash his hands? Did they give their tithe? Did that person avoid associating with ‘unclean’ peoples? Did she eat only foods that have the priest’s stamp of approval?
Actually, we do the same thing today. It’s easy to preach about the evils of drugs, alcohol, or sexual sin. When was the last time you heard a sermon talking about the evils of gossip? slander? malicious conversations? a critical spirit?
God is as concerned about what comes out of us as he is about what we let in.
