'Sin' in the Bible

For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.

For [you can look back and] see what an earnestness and authentic concern this godly sorrow has produced in you: what vindication of yourselves [against charges that you tolerate sin], what indignation [at sin], what fear [of offending God], what longing [for righteousness and justice], what passion [to do what is right], what readiness to punish [those who sin and those who tolerate sin]! At every point you have proved yourselves to be innocent in the matter.

Or did I commit a sin by humbling myself so that you might be exalted, because I preached the gospel of God to you free of charge?

Who is weak without my being weak? Who is led into sin without my intense concern?

I am afraid that when I come my God may again humble me before you and that I may have to grieve over many who formerly lived in sin and have not repented of their impurity, sexual immorality, and promiscuity that they once practiced.
