(17) Therefore . . . .--A difficulty presents itself in this verse--whether the application be general, or a particular comment on the words preceding. Probably both ideas are correct. We learn the converse to the evil of vainglory in life, namely, the good which may be wrought by every one. Occasions of well-doing lie in the abject at our doors, and the pleadings of pity in our very hearts. And thus it is that omission is at times worse than commission; and more souls are in jeopardy for things left undone than for things done. In "The Beautiful Legend" there is a strife between the call of duty to give out a dole of bread to the hungry, and the temptation to linger in religious ecstasy over a vision of Christ. But the true brother knew "to do good," and did it; and, returning at the end of his work, found his cell full of the radiant presence of the Lord, and heard the words of rich approval--

"Hadst thou stayed, I must have fled."

And again, in another succession of thoughts on the text, God has no need of human knowledge; no, nor of our ignorance; "and it is a sin to shut the ears to instruction: it is a duty to get knowledge, to increase in knowledge, to abound in knowledge." Nor must we rest therein, but (2Peter 1:6-7) "add to knowledge temperance, patience, godliness, brotherly kindness, charity."

Verse 17. - Conclusion of the section. "Some have supposed a direct reference to Romans 14:23, 'Whatsover is not of faith is sin.' We can scarcely assume so much; but the correspondence is very remarkable, and St. James supplements St. Paul. It is sin to doubt whether a thing be right, and yet do it. It is also sin to know that a thing is right, and yet to leave it undone" (Dean Scott, in the 'Speaker's Commentary').

4:11-17 Our lips must be governed by the law of kindness, as well as truth and justice. Christians are brethren. And to break God's commands, is to speak evil of them, and to judge them, as if they laid too great a restraint upon us. We have the law of God, which is a rule to all; let us not presume to set up our own notions and opinions as a rule to those about us, and let us be careful that we be not condemned of the Lord. Go to now, is a call to any one to consider his conduct as being wrong. How apt worldly and contriving men are to leave God out of their plans! How vain it is to look for any thing good without God's blessing and guidance! The frailty, shortness, and uncertainty of life, ought to check the vanity and presumptuous confidence of all projects for futurity. We can fix the hour and minute of the sun's rising and setting to-morrow, but we cannot fix the certain time of a vapour being scattered. So short, unreal, and fading is human life, and all the prosperity or enjoyment that attends it; though bliss or woe for ever must be according to our conduct during this fleeting moment. We are always to depend on the will of God. Our times are not in our own hands, but at the disposal of God. Our heads may be filled with cares and contrivances for ourselves, or our families, or our friends; but Providence often throws our plans into confusion. All we design, and all we do, should be with submissive dependence on God. It is foolish, and it is hurtful, to boast of worldly things and aspiring projects; it will bring great disappointment, and will prove destruction in the end. Omissions are sins which will be brought into judgment, as well as commissions. He that does not the good he knows should be done, as well as he who does the evil he knows should not be done, will be condemned. Oh that we were as careful not to omit prayer, and not to neglect to meditate and examine our consciences, as we are not to commit gross outward vices against light!Therefore to him that knoweth to do good,.... This may regard not only the last particular of referring all things to the will of God, the sovereign disposer of life, and all events, which some might have the knowledge of in theory, though they did not practise according to it; but all the good things the apostle had exhorted to, and the contrary to which he had warned from, in this epistle; and suggests, that a Gnostic, or one that knows the will of God, in the several branches of it, revealed in his word,

and doth it not, to him it is sin: it is a greater sin; it is an aggravated one; it is criminal in him that is ignorant of what is good, and does that which is evil, nor shall he escape punishment; but it is much more wicked in a man that knows what is right and good, and ought to be done, and does it not, but that which is evil, and his condemnation will be greater; see Luke 12:47. The omission of a known duty, as well as the commission of a known sin, is criminal.
