The Bible plainly and repeatedly warns believers not to put their trust in men. In addition to this truth, men are not to trust in themselves. As today's passage shows, sometimes God allows circumstances to come into our lives in order to teach us not to trust in ourselves. If any mere mortal could stake a claim to self-trust, it would have been the apostle Paul. He was “circumcised the eighth day,” “an Hebrew of the Hebrews,” and “a Pharisee” (Philippians 3:5). In spite of this, Paul knew these attributes were not sufficient to trust for eternal life. In fact, he counted these things but dung, that he may win Christ (Philippians 3:8). If Paul understood that he could not put his trust in himself or his accomplishments, everyone else should realize that his or her ability or merits are not worthy of trust.
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.
