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.
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.
