The Pharisees repeatedly sought to trap the Lord by attempting to draw Him into controversial discussions. Today's passage demonstrates much more than a simple response to entangling questioning. Interestingly, we learn from the Lord's response that God's law made allowances for man based upon God's understanding of man’s nature. In other words, the Lord Jesus indicated that God gave some of the law simply because of the hardness of man’s heart! Unfortunately, these laws are used today by men to justify decisions contrary to God's will thus further validating the hard-hearted nature of man. In either case, God's ways are never thwarted. God's laws allow even man's wickedness to bring about God's justice and His laws further expose the inherent shortcomings of man. God graciously gave some of His laws to make allowances for man's weaknesses caused by sin.
The Bible admonishes believers to be stedfast and unmoveable (1 Corinthians 15:58). We are to be grounded and settled (Colossians 1:23) in the faith—much like a tree planted by the rivers of waters (Psalm 1:3). Yet, today's passage points to the dangers of a hardened heart set in rebellion. It is likened to a stone and a millstone. We should remain stedfast in our commitment to serve the Lord, yet our hearts should remain tender and pliable to Him and His will. A stony heart hinders the seed of God’s word from taking root (Matthew 13:5-6). This hardness hinders the possibility of spiritual fruit from taking root and maturing. A soft heart and a stedfast walk exhibit the godly balance that God desires for each of us.
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.
