The Bible says that “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). This means that the words proceeding out of our mouths originate in our hearts. When we speak bitter words, it is because there is bitterness within our hearts. David likened bitter words to arrows that pierce the flesh (Psalm 64:3). Our words ought to be “seasoned with salt” (Colossians 4:6); instead, we often allow our words to pierce through others. We tear people down rather than building them up. Why is this? Because we have a root of bitterness growing inside that finds its way from our hearts into and out of our mouths. Those who demean others generally do so because they are bitter. Attempts to justify this behaviour are fruitless because the Lord knows the root of the problem stems from our heart.
As this study has shown, integrity is a matter of the heart, yet it also affects every other aspect of a man’s life. Though men sometimes try to separate an individual’s walk from his true heart’s condition, the Bible reveals the futility of such. Testifying to this truth, the Bible speaks of walking in integrity (Psalm 26:1, 11; Proverbs 19:1; Proverbs 20:7). The Bible says that “by their fruits ye shall know them” (Matthew 7:16, 20) and this principle applies to one’s integrity too. Our passage from Proverbs reveals that as the “just” man walks in his integrity, his children are likewise blessed because of his walk. The secrets of a person’s heart are often unveiled in his walk. Furthermore, a man who walks in his integrity does not fear the judgment of God (Psalm 26:1). Men need integrity of heart, but that integrity must manifest itself in their daily walk.
