In our continued study of hamartia, we find that Christ gave himself for our sins (Gal. 1:4). Paul later asks if Christ is a minister of sin just because we are found to be sinners in seeking to be justified by Christ (2:17). No, God’s purpose through the law (as a forerunner to the gospel) is to “conclude everyone under sin” so that anyone who believes in Jesus might receive the promises (3:22).
In the next book, Ephesians, hamartia is used once and hamartano once. With the former, Paul says that before conversion, we were dead in our transgressions and sins (Eph. 2:1). The latter instance is found where we are commanded to be angry, but to avoid sinning in that anger (4:26).
