James 1:4

But let patience have her perfect work,.... Or effect; or be brought unto perfection; which may denote both the sincerity and continuance of it unto the end, with constancy: patience may be said to be perfect, when it appears to be real and sincere, and not dissembled; for as there may be a feigned faith, a dissembled love, and an hypocritical hope, so likewise a mere show of patience: and certain it is, that as there is a patience which is commendable, there is one that is not, 1Pe 2:

But those sins which bring sufferings, or the weakness and faults men are chargeable with under them, are by no means to be imputed to God, who cannot be the author of sin, but is the author of all good,

Let patience have her perfect work - That is, Continue faithful, and your patience will be crowned with its full reward; for in this sense is εργον, which we translate work, to be understood. It is any effect produced by a cause, as interest from money, fruit from tillage, gain from labor, a reward for services performed; the perfect work is the full reward. See many examples in Kypke.

Let endurance have a perfect work (taken out of the previous "worketh patience" or endurance), that is, have its full effect, by showing the most perfect degree of endurance, namely, "joy in bearing the cross" [MENOCHIUS], and enduring to the end (Mt 10:22) [CALVIN]. ye may be perfect--fully developed in all the attributes of a Christian character.

James calls the converted among the twelve tribes his brethren. Christianity has a great uniting power: it both discovers and creates relationships among the sons of men. It reminds us of the ties of nature, and binds us with the bonds of grace. Every one that is born of the Spirit of God is brother to every other that is born of the same Spirit. Well may we be called brethren, for we are redeemed by one blood; we are partakers of the same life; we feed upon the same heavenly food; we are united to the same living head; we seek the same ends; we love the same Father: we are heirs of the same promises; and we shall dwell for ever together in the same heaven. Wherefore, let brotherly love continue; let us love one another with a pure heart fervently, and manifest that love, not in word only, but in deed and in truth. Whatever brotherhood may be a sham, let the brotherhood of believers be the most real thing beneath the stars. Beginning with this word “brethren,” James shows a true brotherly sympathy with believers in their trials, and this is a main part of Christian fellowship. “Bear ye one another’s burdens, and so fulfil the law of Christ.” If we are not tempted ourselves at this moment, others are: let us remember them in our prayers; for in due time our turn will come, and we shall be put into the crucible. As we would desire to receive sympathy and help in our hour of need, let us render it freely to those who are now enduring trial. Let us remember those that are in bonds, as bound with them, and those that suffer affliction as being ourselves in the body. Remembering the trials of his brethren, James tries to cheer them, and therefore he says, “My brethren, count it all joy when ye fall into divers trials.” It is a part of our high calling to rise ourselves into confidence; and it is also our duty to see that none of our brethren despond, much less despair.

But let patience have her perfect work - Let it be fairly developed; let it produce its appropriate effects without being hindered. Let it not be obstructed in its fair influence on the soul by murmurings, complaining, or rebellion. Patience under trials is fitted to produce important effects on the soul, and we are not to hinder them in any manner by a perverse spirit, or by opposition to the will of God. Every one who is afflicted should desire that the fair effects of affliction should be produced on his mind, or that there should be produced in his soul precisely the results which his trials are adapted to accomplish. That ye may be perfect and entire - The meaning of this is explained in the following phrase - “wanting nothing;” that is, that there may be nothing lacking to complete your character. There may be the elements of a good character; there may be sound principles, but those principles may not be fully carried out so as to show what they are. Afflictions, perhaps more than anything else, will do this, and we should therefore allow them to do all that they are adapted to do in developing what is good in us. The idea here is, that it is desirable not only to have the elements or principles of piety in the soul, but to have them fairly carried out, so as to show what is their real tendency and value. Compare the notes at 1Pe 1:7. On the word “perfect,” as used in the Scriptures, see the notes at Job 1:1. The word rendered “entire” (ὁλόκληροι holoklēroi) means, whole in every part. Compare the notes at 1Th 5:23. The word occurs only in these two places. The corresponding noun (ὁλοκληρία holoklēria) occurs in Act 3:16, rendered “perfect soundness.” Wanting nothing - “Being left in nothing;” that is, everything being complete, or fully carried out.
