Slave to Sin or ?

  And he said to his disciples, "Temptations to sin are sure to come, but woe to the one through whom they come!

It would be better for him if a millstone were hung around his neck and he

were cast into the sea than that he should cause one of these little ones to sin.  Luke 17:1-2

  Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?

  But thanks be to God, that you who were once slaves of sin have become obedient ...  

and, having been set free from sin, have become slaves of righteousness. Romans 6:16-18
