The question concerning duly authorized or appointed authority is crucial. Although the question above originated with the chief priests and elders, it remains a good question. What was the Lord’s authority for the things He was doing, and from what or whom did this authority originate? It is under this microscope that everything in life should be examined. The Lord’s authority was Himself (or His Father), and so it should be with the New Testament believer. Everything believed or done should be believed or done because it is the will of the Lord. Unfortunately, the typical believer today has other competing authorities such as feelings, experience, and even peers that often lead to unscriptural beliefs and works.
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.
