Romans 6:17-18

But Baruch HASHEM (Blessed be G-d) that you used to be avadim (slaves) of Chet, but you gave your mishma'at shebalev (obedience from the heart) to the pattern of Torah (the pnimiyus Torah of Moshiach) to which you were handed over. Having been set free from Chet (sin), you became an eved of the Tzidkat HASHEM (the righteousness of G-d).
