NET
17 But if while seeking to be justified in Christ we ourselves have also been found to be sinners, is Christ then one who encourages sin? Absolutely not!
Darby
17 Now if in seeking to be justified in Christ we also have been found sinners, then [is] Christ minister of sin? Far be the thought.
KJV
17 But if, while we seek to be justified by Christ, we ourselves also are found sinners, [is] therefore Christ the minister of sin? God forbid.
