It is extremely important for everyone to have a functioning conscience. According to Romans 2:15, the conscience works in man to either accuse or else excuse his thoughts. His thoughts further affect his actions. The more often a conscience is ignored, the sooner it loses its capability to work upon man. The same holds true for any conscience defiled by sin. In John chapter 8, as the Lord dealt with the scribes and Pharisees, the desired inner workings of the conscience can be seen. In this instance, the religious leaders brought a woman before the Lord, accusing her of sin. In response, the Saviour suggested that he that was without sin should be the first to cast a stone in judgment. One by one the consciences of the religious leaders convicted them as they turned and walked away.
Sin within a person’s life messes with man’s conscience. It begins by attacking man’s knowledge of God with the end goal of causing a complete rejection of God. Sinful man turns to many different devices in hopes of taking care of his sin-tainted conscience. He may seek to pacify his conscience by doing religious works. He also may try to forget that his conscience has been corrupted by a further turning toward the pleasures of sin. In both cases, he is left with a conscience in need of purging. Where can man turn to find the purging he so strongly desires? According to the Bible, only the blood of Jesus Christ can purge a man’s conscience from dead works to serve the living God (Hebrews 9:14).
Breaking down a compound word into its parts is one of the easiest ways to understand what it means. The word conscience is a compound word made up of the root word science and the prefix con. The prefix con means with while the root word science means knowledge. As is often the case, the built-in dictionary of the Bible helps to solidify this connection, understanding, and definition. In 1 Corinthians 8:7 and 1 Corinthians 8:10, the word conscience is used in conjunction with the mention of knowledge possessed by men. Romans 2:15 makes a similar connection by joining the word conscience with the statement that something is written in the heart. As such, God designed a man’s conscience as an internal tool to place pure and righteous knowledge within an individual that he would otherwise lack.
