James 3:13-18 the difference between men's pretending to be wise, and their being really so.

These verses show the difference between men's pretending to be wise, and their being really so.  He who thinks well, or he who talks well, is not wise in the sense of the Scripture, if he does not live and act well. True wisdom may be know by the meekness of the spirit and temper.  Those who live in malice, envy, and contention, live in confusion; and are liable to be provoked and hurried to any evil work.  Such wisdom comes not down from above, but springs up from earthly principles, acts on earthly motives, and is intent on serving earthly purposes. Those who are lifted up with such wisdom, described by the apostle James, is near to the Christian love, described by the apostle Paul; and both are so described that every man may fully prove the reality of his attainments in them. It has no disguise or deceit. It cannot fall in with those managements the world counts wise, which are crafty and guileful; but it is sincere, and open, and steady, and uniform, and consistent with itself. May the purity, peace, gentleness, a teachable spirit, and mercy shown in all our actions, and the fruits of righteousness abounding in our lives, prove that God has bestowed upon us this excellent gift.

We have some account of true wisdom, with the distinguishing marks and fruits of it: Who is a wise man, and endued with knowledge among you? Let him show out of a good conversation his works with meekness of wisdom, in James 3:13

A truly wise man is a very knowing man: he will not set up for the reputation of being wise without laying in a good stock of knowledge; and he will not value himself merely upon knowing things, if he has not wisdom to make a right application and use of that knowledge. These two things must be put together to make up the account of true wisdom: who is wise, and endued with knowledge? Now these things will follow 1. A good conversation. If we are wiser than others, this should be evidenced by the goodness of our conversation, not by the roughness or vanity of it. Words that inform, and heal, and do good, are the marks of wisdom; not those that look great, and do mischief, and are the occasions of evil, either in ourselves or others. 2. True wisdom may be known by its works. The conversation here does not refer only to words, but to the whole of men's practice; therefore it is said, Let him show out of a good conversation his works. True wisdom does not lie in good notions or speculations so much as in good and useful actions. Not he who thinks well, or he who talks well, is in the sense of the scripture allowed to be wise, if he do not live and act well. 3. True wisdom may be known by the meekness of the spirit and temper: Let him show with meekness, It is a great instance of wisdom prudently to bridle our own anger, and patiently to bear the anger of others. And as wisdom will evidence itself in meekness, so meekness will be a great friend to wisdom; for nothing hinders the regular apprehension, the solid judgment, and impartiality of thought, necessary to our acting wisely, so much as passion. When we are mild and calm, we are best able to hear reason, and best able to speak it. Wisdom produces meekness, and meekness increases wisdom. James 3:14 If we have bitter envying and strife

If you be under the influence of an unkind, fierce, and contemptuous spirit, even while attempting or pretending to defend true religion, do not boast either of your exertions or success in silencing an adversary; you have no religion, and no true wisdom, and to profess either is to lie against the truth. Here is given excellent advice on this subject:

More than his sickness or his poverty? Pretend what you will, and think yourselves ever so wise, yet you have abundance of reason to cease your glorying, if you run down love and peace, and give way to bitter envying and strife. Your zeal for truth or orthodoxy, and your boasts of knowing more than others, if you employ these only to make others hateful, and to show your own spite and heart-burnings against them, are a shame to your profession of Christianity, and a downright contradiction to it. Lie not thus against the truth." James 3:15

Observe, 1. Envying and strife are opposed to the meekness of wisdom. The heart is the seat of both; but envy and wisdom cannot dwell together in the same heart. Holy zeal and bitter envying are as different as the flames of seraphim and the fire of hell. 2. The wisdom that is from above is peaceable. Peace follows purity, and depends upon it. Those who are truly wise do what they can to preserve peace, that it may not be broken; and to make peace, that where it is lost it may be restored. In kingdoms, in families, in churches, in all societies, and in all interviews and transactions, heavenly wisdom makes men peaceable.3. It is gentle, not standing upon extreme right in matters of property; not saying nor doing any thing rigorous in points of censure; not being furious about opinions, urging our own beyond their weight nor theirs who oppose us beyond their intention; not being rude and overbearing in conversation, nor harsh and cruel in temper. Gentleness may be opposed to all these 4. Heavenly wisdom is easy to be entreated, eupeithēs; it is very persuadable, either to what is good or from what is evil. There is an easiness that is weak and faulty; but it is not a blameable easiness to yield ourselves to the persuasions of God's word, and to all just and reasonable counsels or requests of our fellow-creatures; no, nor to give up a dispute, where there appears a good reason for it and where a good end may be answered by it. 5. Heavenly wisdom is full of mercy and good fruits, inwardly disposed to every thing that is kind and good, both to relieve those who want and to forgive those who offend, and actually to do this whenever proper occasions offer. 6. Heavenly wisdom is without partiality. The original word, adiakritos, signifies to be without suspicion, or free from judging, making no undue surmises nor differences in our conduct towards one person more than another. The margin reads it, without wrangling, not acting the part of sectaries, and disputing merely for the sake of a party; nor censuring others purely on account of their differing from us. The wisest men are least to be censurers. 7. That wisdom which is from above is without hypocrisy. It has no disguises nor deceits. It cannot fall in with those managements which the world counts wise, which are crafty and guileful; but it is sincere and open, steady and uniform, and consistent with itself. O that you and I may always be guided by such wisdom as this! that with Paul we may be able to say, Not with fleshly wisdom, but in simplicity and godly sincerity, by the grace of God, we have our conversation. And then, lastly, true wisdom will go on to sow the fruits of righteousness in peace, and thus, if it may be, to make peace in the world, James 3:18And that which is sown in peace will produce a harvest of joys. Let others reap the fruits of contentions, and all the advantages they can propose to themselves by them; but let us go on peaceably to sow the seeds of righteousness, and we may depend upon it our labour will not be lost. For light is sown for the righteous, and gladness for the upright in heart; and the work of righteousness shall be peace, and the effect of righteousness quietness and assurance for ever.
