A man’s conscience is likened to a muscle. When a man exercises his conscience, it becomes strong and increasingly useful. It can protect when the enemy attacks and keep that man from being taken captive. When the conscience is ignored, it deteriorates and becomes weak and less dependable. The apostle Paul warned the believers at Corinth about defiling the weak conscience of others who might not be as strong in the faith. It was so important that they were to be willing to refuse to eat meat, a perfectly acceptable food, if eating it meant someone else’s conscience was going to be harmed. According to Paul, damaging someone’s conscience was to sin against that brother.
Those with a broad understanding of scripture recognize that charity functions as the peak of Christianity (see 1 Corinthians 13:13). Yet, few students consider the fact that a good conscience is mentioned within the same context (1 Timothy 1:5). A good conscience was a key component of Paul’s charge to young Timothy (1 Timothy 1:18-19). It was also part of Peter’s admonition to the believers to whom he wrote (1 Peter 3:16). In Paul’s own life, it was one of his chief concerns to serve the Lord with a good or a pure conscience (1 Timothy 3:9; 2 Timothy 1:3). It may require work, but the early believers saw the importance of putting forth the effort to maintain a good conscience.
According to the Bible, a man’s conscience is worth protecting. So much so, that a man’s decisions in life should often be dictated by how his choices will affect his conscience as well as those who know of his decisions. Paul summed up this thought process when he said, “Even as I please all men in all things, not seeking mine own profit, but the profit of many, that they may be saved.” Sometimes the emphasis placed upon a concern for one’s conscience moves an individual to submit himself to those who rule, perhaps even unworthily (Romans 13:5). Other times, it may cause a man to suffer wrongfully, enduring grief. Either way, a man who cares about the conscience will allow its well-being to change his life.
Man’s conscience has proven to be one of the most undervalued possessions held by man. The Bible shows that the apostle Paul understood the value of his conscience. He exercised himself to ensure that his conscience was void of offence toward both God and other men. When Paul testified before the council, he could proclaim that he had “lived in all good conscience before God” to that day (Acts 23:1). This did not just happen by chance because Paul described his efforts as exercise (work). It took constant effort. It required willingly denying himself and considering the will of the Lord. The apostle Paul is with the Lord, but the same principles hold true for anyone else who desires the testimony of a good conscience void of offence.
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.
