Jamieson, Fausset & Brown

instructing--Greek, "disciplining," instructing with correction, which those who deal in "uninstructive" or "undisciplined questions" need (see on Ti2 2:23; Ti1 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" (Ti1 2:4), their minds being corrupted (Ti2 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" (Act 5:31).
