ISB ~ Romans 6 v16

obedient slaves:It would be absurd for a slave, recently purchased to serve a new master (righteousness), to continue to serve the old one (sin). The first master leads to destruction and death (6:23), and the new master to sanctification and life (6:22).

righteousness:A baptismal gift (5:17) as well as a future hope (Gal 5:5). Paul here refers to the righteous status that comes with the final justification of the saints at the Judgment (2:13).
