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.
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.
Paul and Barnabas admonished the heathen to turn from “vanities unto the living God.” One cannot trust in the Lord and simultaneously trust in anything else. In order for an individual to be saved, he must repent of trusting in anything other than the Lord. One aspect of repentance involves ceasing to trust vanity and turning one’s faith toward the living and true God. This saving faith needs to become a living faith following salvation. Believers should consistently turn from “vain thoughts” and love the law of God (Psalm 119:113). They should turn from the vain labours that spend their strength for nought (Isaiah 49:4) and be “steadfast . . . in the work of the Lord” knowing that their “labour is not in vain in the Lord” (1 Corinthians 15:58). Additionally, believers should turn from “vain words” (Ephesians 5:6) and hold “forth the word of life” (Philippians 2:16).
The Lord redeemed Israel out of Egypt for the purpose of worshipping Him. Instead of willingly serving Him, the nation of Israel turned to vanities. In doing so, they ignited the fire of God’s anger (Deuteronomy 32:21-22). Ultimately, God chose to provoke Israel to jealousy with a people “which are not a people” – the Gentiles. Since Israel had provoked the Lord to anger with their vanities, He was going to use Gentiles, whom Israel knew to be “not a people,” to provoke Israel to anger. The Lord expects the redeemed to flee vanity and give themselves wholly to His work, worship, and will. The Lord has now redeemed Jew and Gentile “for his name” (Acts 15:14), and He expects the same from each of us.
