2:22-26 The more we follow that which is good, the faster and the further we shall flee from that which is evil. The keeping up the communion of saints, will take us from fellowship with unfruitful works of darkness. See how often the apostle cautions against disputes in religion; which surely shows that religion consists more in believing and practising what God requires, than in subtle disputes. Those are unapt to teach, who are apt to strive, and are fierce and froward. Teaching, not persecution, is the Scripture method of dealing with those in error. The same God who gives the discovery of the truth, by his grace brings us to acknowledge it, otherwise our hearts would continue to rebel against it. There is no peradventure, in respect of God's pardoning those who do repent; but we cannot tell that he will give repentance to those who oppose his will. Sinners are taken in a snare, and in the worst snare, because it is the devil's; they are slaves to him. And if any long for deliverance, let them remember they never can escape, except by repentance, which is the gift of God; and we must ask it of him by earnest, persevering prayer.
25. instructing—Greek, "disciplining," instructing with correction, which those who deal in "uninstructive" or "undisciplined questions" need (see on 2Ti 2:23; 1Ti 1:20).
those that oppose themselves—Greek, "oppositely affected"; those of a different opinion.
if … peradventure—Greek, "if at any time."
repentance—which they need as antecedent to the full knowledge (so the Greek for 'acknowledgment') of the truth" (1Ti 2:4), their minds being corrupted (2Ti 3:8), and their lives immoral. The cause of the spiritual ignorance which prompts such "questions" is moral, having its seat in the will, not in the intellect (Joh 7:17). Therefore repentance is their first need. That, not man, but God alone can "give" (Ac 5:31).
