Being spiritually reproductive
Through good workmanship
2 Tim 2:14–26 contains Paul's instructions to Timothy about leading other believers. Two important refrains here are: avoiding pointless bickering, and holding to sound biblical teachings.
Arguments over non-essential issues quickly turn into feuds, poisoning the body of Christ just as gangrene attacks the physical body. Paul names specific false teachers, but brings a note of compassion, reminding Timothy that gentleness and patience are key. After all, those who do not believe are not our enemies, but those we are trying to rescue from the control of the Devil.
Timothy is meant to specifically teach others to avoid bickering, an issue that Paul had already addressed in 1 Timothy. Paul gives two reasons why arguing over words is unhelpful. First, there is no benefit to be gained by arguing over irrelevant details of Scripture (1 Tim 1:3–4).
By this, Paul does not suggest taking a shallow view of the Bible. Rather, he means to avoid conflict over disputable issues (Rom. 14:1). Paul specifically had in mind the false teachers mentioned in 1 Timothy who attempt to re-interpret the Torah, seeking to make Christians obey Jewish laws.
Second, Paul said arguing about words "only ruins the hearers", and listeners were being "ruined" by such talk. The Greek word here is katastroph?, including the idea of destruction, or being overthrown.
In our day, we ought to rightly divide the Word of truth, exercising precision and accuracy, taking the literal sense of the text as its intended meaning, observing what the text means in its context, and to its original audience, and checking that its meaning agrees with other passages of Scripture. Only then can we be approved unto God, workmen that need not to be ashamed when our work is tested.
