James 1:4

Let - To hinder or obstruct.

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.

That ye may be perfect and entire - Τελειοι, Fully instructed, in every part of the doctrine of God, and in his whole will concerning you. Ὁλοκληροι, having all your parts, members, and portions; that ye may have every grace which constitutes the mind that was in Christ, so that your knowledge and holiness may be complete, and bear a proper proportion to each other. These expressions in their present application are by some thought to be borrowed from the Grecian games: the man was τελειος, perfect, who in any of the athletic exercises had got the victory; he was ὁλοκληρος, entire, having every thing complete, who had the victory in the pentathlon, in each of the five exercises. Of this use in the last term I do not recollect an example, and therefore think the expressions are borrowed from the sacrifices under the law. A victim was τελειος, perfect, that was perfectly sound, having no disease; it was ὁλοκληρος, entire, if it had all its members, having nothing redundant, nothing deficient. Be then to the Lord what he required his sacrifices to be; let your whole heart, your body, soul, and spirit, be sanctified to the Lord of hosts, that he may fill you with all his fullness.

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 1 Peter 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 1 Thessalonians 5:23. The word occurs only in these two places. The corresponding noun (ὁλοκληρία holoklēria) occurs in Acts 3:16, rendered "perfect soundness."

Wanting nothing - "Being left in nothing;" that is, everything being complete, or fully carried out.

1:4 Let patience have its perfect work - Give it full scope, under whatever trials befal you. That ye may be perfect and entire - Adorned with every Christian grace. And wanting nothing - Which God requires in you.
