John 16:8-11

8And He, when He comes, will convict the world about [the guilt of] sin [and the need for a Savior], and about righteousness, and about judgment:

9about sin [and the true nature of it], because they do not believe in Me [and My message];

10about righteousness [personal integrity and godly character], because I am going to My Father and you will no longer see Me;

11about judgment [the certainty of it], because the ruler of this world (Satan) has been judged and condemned.
