Romans 6:14-16

For sin will have no mastery over you, because you are not under law but under grace. What then? Shall we sin because we are not under law but under grace? Absolutely not! Do you not know that if you present yourselves as obedient slaves, you are slaves of the one you obey, either of sin resulting in death, or obedience resulting in righteousness?

Grace commands obedience to righteousness in Christ. Part of that obedience is realized by our faith in Jesus as our Savior, and part is realized through Jesus' Lordship as rebirth and restoration floods its way through our hearts, minds, and lives. Grace does not command willfully embracing sin or evil because "we are not under the law", and it is not an excuse to live a life continuously overwhelmed by sin. Falling to sin is one thing, but jumping into sin is another. The Holy Spirit, alive, well, and working for our good and His good purpose will lead us safely through the battlegrounds of life. Our dependence upon Jesus must be complete! His grace must be sufficient for us! Through that commitment, that obedience by grace to Christ, His power will be perfected in and through our lives.
