An assault upon the conscience of man is indicative of the “latter times.” As men depart from the faith and give heed to seducing spirits and doctrines of devils, their consciences become so weak that they show very little sign of life. The Bible describes it as a searing of their consciences with a hot iron. Initially, there is great pain in the sin and the conscience feels the pain. Yet, eventually, the conscience becomes so seared that it is numb. At that point, the conscience loses its ability to warn the believer of sin. It further loses the ability to get the believer’s attention when he is on the verge of danger. Eventually, men speak lies in hypocrisy and do not care or feel any remorse for their wickedness.
The apostle Paul knew the importance of having believers pray for him. Among the things for which he requested prayers, Paul specifically asked for prayer that he might maintain a good conscience, living honestly in all things. He did not trust the condition of his conscience to his own efforts but depended upon the Lord’s willingness to hear and answer the prayers of the saints. Unfortunately, far too many Christians have become entirely self-reliant and self-trusting. As such, fewer believers request or take part in prayer for another man’s conscience. Instead, prayer has generally been reduced to one’s needs whether they are physical, material, or financial. Scriptural Christianity places a greater concern for the conscience.
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).
Only a foolish man thinks he can hide anything from the Lord. This includes his thought life. The Lord knows all man’s thoughts (1 Chronicles 28:9) which includes the good (Malachi 3:16) and the bad (Psalm 94:11). David expressed this truth to the Lord when he said, “Thou knowest . . . my thought afar off. . . . For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether” (Psalm 139:2-4). The Lord Jesus Christ often exhibited this capability during His earthly ministry (Matthew 12:25; Luke 5:22; Luke 6:8; Luke 9:47; Luke 11:17). Even the written word of God reveals this ability by being “a discerner of the thoughts and intents of the heart” (Hebrews 4:12).
