And because iniquity shall abound, the love of many shall wax cold (Matthew 24:12).
The word that is translated iniquity is the Greek word anomia which can also be translated wickedness. And, the word translated abounds is the Greek word plethuno which means to increase or multiply. The same Greek word translated iniquity is also used to describe the religious leaders in Jesus’ day (Matthew 23:28) and the mystery of iniquity when Antichrist will be revealed (2Thessalonians 2:7).
When Jesus Christ returns He will send His angels to gather those who do iniquity (Matthew 13:41-42); and when speaking of the judgment day, Jesus mentions some who prophesied in His name, and refers to them as workers of iniquity (Matthew 7:21-23).
In Matthew 24:11 Jesus mentions false prophets that will also arise. It is quite possible, then, that these false prophets are at least some of the false prophets referred to in Matthew 7:21-23. Since Jesus referred to them as workers of iniquity, it may be at least partially through them that iniquity abounds as mentioned in the next verse, Matthew 24:12. One of the results of their work is that many will be deceived. As a result of the iniquity the love of many will grow cold, and some may even fall away from the faith as is indicated will happen during this time.
