Romans 6:17-19

Moffatt(i) 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.
