Matthew 24:12

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 ... - 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.
