Because iniquity will abound. How far and wide this evil extends every person ought to know, but there are very few who observe it. For in consequence of the superior clearness with which the light of the gospel discovers the malice of men, even good and properly regulated minds grow cool, and almost lose the desire to exercise benevolence. Each of them reasons thus with himself, that the duties which they perform to one person, or to another, are thrown away, because experience and daily practice show that almost all are ungrateful, or treacherous, or wicked. This is unquestionably a weighty and dangerous temptation; for what could be more unreasonable than to approve of a doctrine, by which the desire of doing good, and the rigor of charity, appear to be diminished? And yet when the gospel makes its appearance, charity, which ought to kindle the hearts of all men with its warmth, rather grows cool. But we must observe the source of this evil, which Christ points out, namely, that many lose courage, because through their weakness they are unable to stem the flood of iniquity which flows on every hand. Christ requires from his followers, on the other hand, such courage as to persist in striving against it; as Paul also enjoins us not to be weary of performing deeds of kindness and beneficence, (2-Thessalonians 3:13.) Although, then, the charity of many, overwhelmed by the mass of iniquities, should give way, Christ warns believers that they must surmount this obstacle, lest, overcome by bad examples, they apostatize. And therefore he repeats the statement, that no man can be saved, unless he strive lawfully, (2-Timothy 2:5,) so as to persevere to the end

And because iniquity - The word "iniquity" here seems to include the cruelty of the Jews and Romans in their persecutions; the betraying of Christians by those who professed to be such; and the pernicious errors of false prophets arid others. The effect of all this would be, that the ardor of feeling of many Christians would be lessened. The word "wax" means to "become." It is an old Saxon word, not used now in this sense except in the Bible. The fear of death, and the deluding influence of false teachers, would lessen the zeal of many timid and weak professors; perhaps, also, of many real but feeble Christians.

The love of many shall wax cold - By reason of these trials and persecutions from without, and those apostasies and false prophets from within, the love of many to Christ and his doctrine, and to one another, shall grow cold. Some openly deserting the faith, as Matthew 24:10; others corrupting it, as Matthew 24:11; and others growing indifferent about it, Matthew 24:12. Even at this early period there seems to have been a very considerable defection in several Christian Churches; see Galatians 3:1-4; 2-Thessalonians 3:1, etc.; 2-Timothy 1:15.

And because iniquity shall abound,.... Meaning, either the malice and wickedness of outrageous persecutors, which should greatly increase; or the treachery and hatred of the apostates; or the errors and heresies of false teachers; or the wickedness that prevailed in the lives and conversations of some, that were called Christians: for each of these seem to be hinted at in the context, and may be all included, as making up the abounding iniquity here spoken of; the consequence of which would be,
the love of many shall wax cold. This would be the case of many, but not of all; for in the midst of this abounding iniquity, there were some, the ardour of whose love to Christ, to his Gospel, and to the saints, did not abate: but then there were many, whose zeal for Christ, through the violence of persecution, was greatly damped; and through the treachery of false brethren, were shy of the saints themselves, not knowing who to trust; and through the principles of the false teachers, the power of godliness, and the vital heat of religion, were almost lost; and through a love of the world, and of carnal ease and pleasure, love to the saints was grown very chill, and greatly left; as the instances of Demas, and those that forsook the Apostle Paul, at his first answer before Nero, show. This might be true of such, who were real believers in Christ; who might fall under great decays, through the prevalence of iniquity; since it does not say their love shall be lost, but wax cold.

Because iniquity shall abound, etc. Immorality eats out the heart of religion.
