The Bible clearly points out that by God’s grace the apostle Paul laid the foundation which is Jesus Christ and Him crucified. All those who have come after the apostle Paul have built upon that foundation. It is with this in mind that Paul warned believers to take heed how they built upon the foundation. The foundation has been laid, and no other foundation can be laid, but each believer must carefully examine the means by which he builds upon Christ. Not only should believers take heed to their daily walk, but self-examination is also necessary in their manner of service for the Lord Jesus Christ. Each believer should search the scriptures to ensure that his efforts glorify the Lord. Far too much effort is self-serving and selfish and not God-centric. Self-examination helps define one’s motives.
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).
