Sinner - Vine's Expository Dictionary of New Testament Words
Sinner[ 1,,G268, hamartolos ]
lit., one who misses the mark" (a meaning not to be pressed), is an adjective, most frequently used as a noun (See SINFUL); it is the most usual term to describe the fallen condition of men; it is applicable to all men, Romans 5:8, Romans 5:19. In the Synoptic Gospels the word is used not infrequently, by the Pharisees, of publicans (tax collectors) and women of ill repute, e.g., "a woman which was in the city, a sinner," Luke 7:37; "a man that is a sinner," Luke 19:7. In Galatians 2:15, in the clause "not sinners of the Gentiles," the Apostle is taking the Judaizers on their own ground, ironically reminding them of their claim to moral superiority over Gentiles; he proceeds to show that the Jews are equally sinners with Gentiles.
Note: In Luke 13:4, AV, opheiletes, "a debtor," is translated "sinners" (RV, "offenders;" RV and AV marg., "debtors").
