2 Corinthians 3:9
If the ministry that brought condemnation was glorious, how much more glorious is the ministry that brings righteousness. (NIV)
For if there was glory in the ministry of condemnation, much more does the ministry of justification abound in glory! (NRSV)
If glory accompanied the ministry that brought condemnation, how much richer in glory must be the ministry that brings acquittal! (REB)
For if the service of bringing judgement against [is, or was] glory, how much more in glory excels the service of righteousness (making just). (My translation).
Why note this?
Because recently on ADU there have been discussions about Doug Campbell's recent works, The Deliverance of God and Pauline Dogmatics, which have raised the question how important "justification by faith" is to Paul's gospel.
2 Corinthians 3:9 implies is it very important because "service of righteousness/justification" sums up the gospel when compared to the Law.
