Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
As already discussed, the word salvation is used throughout the word of God, but depending upon the context, the intended meaning varies. Failure to understand the different usages has led many to espouse some of the most egregious false doctrines. It is important to understand that the foundational meaning of the word salvation refers to deliverance. The vast majority of occurrences in the word of God actually refer to physical deliverance rather than a soul’s salvation. The word salvation can often be found within the context to describe the time when someone received deliverance from a specific trial or a threatening enemy. The most common usage today among believers relates to spiritual deliverance offered through the finished work of Jesus Christ.
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.
