17 In the past you were slaves to sin—sin controlled you. But thank God, you fully obeyed what you were taught. 18 You were made free from sin, and now you are slaves to what is right. 19 I use this example from everyday life because you need help in understanding spiritual truths. In the past you offered the parts of your body to be slaves to your immoral and sinful thoughts. The result was that you lived only for sin. In the same way, you must now offer yourselves to be slaves to what is right. Then you will live only for God.
