13 you must not let sin have your members for the service of vice, you must dedicate yourselves to God as men who have been brought from death to life, dedicating your members to God for the service of righteousness.
14 Sin must have no hold over you, for you live under grace, not under law.
15 What follows, then? Are we 'to sin, because we live under grace, not under law'? Never!
16 Do you not know you are the servants of the master you obey, of the master to whom you yield yourselves obedient, whether it is Sin, whose service ends in death, or Obedience, whose service ends in righteousness?
17 Thank God, though you did serve sin, you have rendered whole-hearted obedience to what you were taught under the rule of faith;
18 set free from sin, you have passed into the service of righteousness.
19 (I use this human analogy to bring the truth home to your weak nature.) As you once dedicated your members to the service of vice and lawlessness, so now dedicate them to the service of righteousness that means consecration.
