James 1:19,20

Wherefore As if he had said, Since you are regenerated, and that by the word of God, therefore let every man be swift to hear That word; let him be willing and desirous to receive instruction from it, and therefore diligent in embracing all opportunities of hearing it; slow to speak To deliver his opinion in matters of faith, that he does not yet well understand. Persons half instructed frequently have a high opinion of their own knowledge in religious matters, are very fond of teaching others, and zealous to bring them over to their opinions. That the converted Jews were fond of being teachers, we learn from James 3:1; 1 Timothy 1:7. Slow to wrath Against those that differ from him. Intemperate religious zeal is often accompanied by a train of bad passions, and particularly with anger against those who differ from us in opinion. The Jews, even the Jewish Christians to whom this letter was chiefly written, were very faulty in this respect. The apostle, however, may be understood as cautioning his readers against easily yielding to provocation in any respect whatever, and especially when injuriously treated by their persecutors. For the wrath of man Even when it appears in the garb of religious zeal, worketh not But, on the contrary, greatly obstructs, the righteousness of God Instead of promoting the cause of true religion in the world, it is a reproach to it, and a means of exciting the prejudices of mankind against it. Persecution, in particular, the effect of the wrath of man, if violent, may make men hypocrites, by forcing them to profess what they do not believe; but it has no influence to produce that genuine faith which God accounts to men for righteousness. Nothing but rational arguments, with the illumination of the Spirit of God, can do this.
