Romans 6:16-18

16Don’t you realize that you become the slave of whatever you choose to obey? You can be a slave to sin, which leads to death, or you can choose to obey God, which leads to righteous living.

17Thank God! Once you were slaves of sin, but now you wholeheartedly obey this teaching we have given you.

18Now you are free from your slavery to sin, and you have become slaves to righteous living.
