Every time Susan opens her mouth, it sounds like the blare of an ambulance siren. This TV commercial uses humor to indicate that a dental problem could reveal a more serious physical ailment. So she’d better see her dentist soon!

The commercial made me think about what comes out of my mouth when I open it. Jesus said that our words come from our heart (Matt. 15:18). He offended the Pharisees when He said, “Not what goes into the mouth defiles a man; but what comes out of the mouth, this defiles a man” (vv.11-12). They thought they were right with God because they followed strict rules, including ritual cleansing of their hands before eating and eating only “clean” foods. Jesus upset their pride.

Jesus upsets our pride too. We may think we’re godly people because we go to church regularly or pray, but then we gossip or talk about people behind their backs. James 3:9-10 says, “With [our tongue] we bless our God and Father, and with it we curse men . . . . Out of the same mouth proceed blessing and cursing. . . . These things ought not to be so.”

If a siren blares from our mouth when we open it, we need to examine our heart and ask the Lord to forgive us and to help us be a blessing to others.
