Note 5 at Mt 24:12: The only reason that an abundance of iniquity would make people's love for the Lord wax cold is if they were not separated from that iniquity. As with Lot, righteous people can vex their souls from day to day by hearing and seeing the unlawful deeds of the ungodly (2Pe 2:8). This is the reason for the commands and promises of 2Co 6:14-18. "Be not deceived: evil communications corrupt good manners" (1Co 15:33).
