The Greek word anomia is rendered variously — as iniquity, or unrighteousness, or transgression of the law. We will begin with the places where it is translated as iniquity.
Jesus says that in the last day, He will dismiss those who claimed to have done great works in His name, but who were actually “workers of iniquity” (Matt. 7:23). Also at the last day, the Son of Man will send out His angels and they will gather out of His kingdom all things that offend, along with all those who do iniquity (Matt. 13:41). In His great rebuke of the theologians, Jesus calls them out as those who are “full of hypocrisy and iniquity” (Matt. 23:28). And in His great prophecy of the destruction of Jerusalem, Jesus said that one of the warning signs would be that iniquity would abound (Matt. 24:12).
The apostle Paul pronounces a blessing on those who iniquities are forgiven, whose sins are covered (Rom. 4:7). The characteristic of the unconverted is that they yield their members from iniquity to iniquity (Rom. 6:19).
In 2 Th. 2:7, Paul says that the mystery of iniquity was already at work.
Jesus Christ died on the cross in order to redeem us from all iniquity (Tit. 2:14). God loves righteousness and He hates iniquity (Heb. 1:9). One of the great features of the new covenant is that God will remember our sins and our iniquities no longer (8:12; 10:17).
