This isn't about tweaking your bad habits; it's about a complete change of ownership.
Paul's imagery of slavery highlights that this is a fundamental transfer of allegiance. We didn't just clean up our act; we were bought out of one kingdom and transferred into another.
- The old master (sin) demanded total service and produced only death and destruction.
- The new master (God's righteousness) claims us and empowers us for a life of growth in holiness.
This transfer is so complete that Paul can say, 'if you know that you were freed from sin, you became slaves of righteousness.' It’s not a choice between being a slave and being free; it’s a choice between which master you will serve. Our 'infirmity' doesn't excuse continued slavery to sin; rather, it calls us to embrace the new, liberating servitude to righteousness.
