Romans 8:12 marks a transition point in Paul's argument, and it reads almost like an unfinished sentence — because in a sense, it is. Paul says "we are debtors, not to the flesh," but he never actually states what we ARE debtors to. He leaves that implied, because the whole preceding passage (Romans 8:1-11) has already made it obvious: believers are debtors to the Spirit, to God, to the new life given to them through Christ.

Verse 12 draws the practical conclusion from that contrast: since the Spirit now lives in you, you are no longer obligated to your
