'In Sin' in the Bible

What shall we say then? Shall we continue in sin that grace may abound?

Slaves, be obedient to those who are your masters according to the flesh, with fear and trembling, in sincerity of heart, as to Christ;

Slaves, in everything obey those who are your masters according to the flesh, not with eye-service, as men-pleasers, but in sincerity of heart, fearing the Lord.

Those who continue in sin, rebuke in the presence of all, so that the rest also may be fearful of sinning.
