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.
A man’s conscience resides within, yet its expression can be witnessed by others. Because of the testimony of his conscience, Paul rejoiced. According to scripture, that testimony was manifest to the world but especially among the people of God. Those who knew Paul knew that he served the Lord “in simplicity and godly sincerity.” He did not do everything right, but he exhibited a passion of heart to do right in all that he did. No doubt, this was a wonderful example to other believers who looked to Paul for guidance. They saw a man who sincerely loved the Lord and others and also gave every effort possible not to offend either.
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.
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.
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.
Sometimes the most difficult and significant tasks involve the simplest truths. For instance, every Christian should quickly learn that vengeance belongs unto the Lord. God confirms as much throughout scripture (Deuteronomy 32:35; Psalm 94:1; Romans 12:19; Hebrews 10:30). This should be understandable as only the Lord has all the necessary information to execute just vengeance 100 percent of the time. When man attempts to execute vengeance, he often does so out of an improper motive or without key information of the evil that appears to have been done. Furthermore, when a believer takes vengeance into his own hands, he robs the Lord of His right and responsibility to exact vengeance at the right time and in the right manner.
Following a shipwreck, Paul, and those with him, escaped to an island called Melita. The Bible describes the natives as a barbarous people who were not completely void of truth. They demonstrated kindness toward those who had escaped the sea by kindling a fire for them. Paul helped the natives by gathering a bundle of sticks to cast upon the fire. As he cast the sticks on the fire, a viper came out of the heat and fastened on Paul’s hand. Immediately, the barbarians assumed Paul to be a murderer who was being recompensed for his wickedness. Even though these people did not know the Lord, they had some of His laws written in their consciences..
A simplistic view of vengeance involves the retribution of an evil deed. The first (Genesis 4:15) and last (Jude 7) mention of the word vengeance substantiates this definition. The Bible uses words like recompence (Deuteronomy 32:35), reward (Deuteronomy 32:41), punishments (Psalm 149:7), avenge (Jeremiah 46:10), revenge (Ezekiel 25:15), and repay (Romans 12:19) as descriptive words for vengeance. With this in mind, it is clear that vengeance is the just punishment as a consequence upon those who violate the laws of God. It is not the dispensing of wrath without cause but is specific punishment exacted for specific crimes committed.
