The Greek word anomia

Found in Mt. 7:23; 13:41; 23:28; 24:12; Rom. 4:7; 6:19; 2 Cor. 6:14; 2 Thess. 2:3 (some translations), 7; Tit. 2:14; Heb. 1:9; 8:12; 10:17; 1 Jn. 3:4, the Greek noun “anomia” meant “lawlessness,” “without law,” or “sin.”  This seems to be the strongest for sin in the Greek New Testament.

At the end of time Jesus will tell some religious people who will claim to be Christians they were workers of “iniquity” and He never knew them (Mt. 7:23).  Paul’s use of this word in Rom. 4:7 suggests God had some means to offer forgiveness of sins under the Old Testament era.  Christians are cleansed of all “iniquity” (Tit. 2:14 and compare Heb. 8:12; 10:17 where this same word is used).  Deity is said to hate “iniquity” (Heb. 1:9).  Of all the verses that use this noun, 1 Jn. 3:4 is probably the best known passage.
