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 that there would be times when Timothy, as a minister of the gospel, would have to rebuke or correct others. However, Timothy was not to rebuke others on a whim. In fact, Paul specifically laid out two premises which Timothy’s rebuke should follow: “with all longsuffering and doctrine.” Timothy was to rebuke others while suffering with them for a long time, thus longsuffering. He was to exhibit grace by offering others the opportunity to rectify their areas of failure. At the same time, he was to rebuke others with sound doctrine and not simply based upon mere opinion. This was going to be even more necessary as some would begin to depart from sound doctrine and practice (2 Timothy 4:3-4).
