JMNT(i)
9 having seen and thus knowing and perceiving that Christ, being aroused and raised forth from out of the midst of dead folks, is no longer dying. His death is no longer exercising ownership (or: Death is no longer being lord or exerting mastery pertaining to Him; or: Death, from Him, is no longer functioning as a lord),
10 for what He died (or: You see, [the death] which He died), He died for the Sin (or: by the Failure; in the deviation; to the Sin; with the Error) once for all [time] (or: at once and only once); yet what He lives (or: Yet [the life] which He continues to live), He continues living in God (for God; to God; by God; with God).
11 Thus you folks, also, be logically considering (reckoning, accounting and concluding) yourselves to exist being dead ones, indeed, by the failure to hit the target (or: in the Sin; to the deviation), yet ones continuously living by God (in God; for God; to God; with God), within Christ Jesus, our Owner (or: in union with [the] Anointed Jesus, our Lord and Master).
