2 Timothy 2:14
14Remind them of these things, charging them in the sight of the Lord that they don’t argue about words to no profit, to the subverting of those who hear.
Remind them of these things—the gospel just recited—and charge them in the sight of the Lord that they don’t argue about words. Word-fights do no good; they ruin hearers. The trustworthy saying is to be pressed, not replaced by clever disputes.
A ruined hearer is a spiritual casualty, not a stage effect. Charge before God because people can still be overturned. Ministry that loves ingenuity more than edification harms those who might yet believe.
Calvin: these things are of such importance that a good minister ought never to be weary of exhibiting them. Solemn charging before the Lord is meant to strike terror. Disputing about words is condemned as useless and as subverting the hearers; Satan uses quarrels to disturb the weak and overthrow their faith.
Edification is the only aim. Speculative theology that tends to ostentation is a danger to the church. God preserves his people, and he uses this severe charge as a means to fence them from ruinous talk.
