He who has a deceitful heart finds no good, and he who has a perverse tongue falls into evil. (Proverbs 17:20, NKJV)
The heart and the tongue are connected. Jesus said, “A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things” (Matthew 12:35). In today’s verse, the deceitful heart (“crooked heart,” ESV) finds nothing good in others. Truly, “to those who are defiled and unbelieving nothing is pure” (Titus 1:15). Comparisons, complaints and disputes pour out of the mouth of the person whose heart is crooked and deceitful. As God’s children we are to “do all things without complaining and disputing” (Philippians 2:14). One way to see good in others instead of falling into contentiousness is to adorn our hearts with honesty, truth and love (Ephesians 4:25, 15). Unrestrained hearts unleash verbal grenades that maim and kill relationships and souls. We must constantly remember that tongue control begins with heart control (James 3:2, 8).
