John 16:7-11

But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper (Comforter, Advocate, Intercessor—Counselor, Strengthener, Standby) will not come to you; but if I go, I will send Him (the Holy Spirit) to you [to be in close fellowship with you]. And 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: about sin [and the true nature of it], because they do not believe in Me [and My message]; about righteousness [personal integrity and godly character], because I am going to My Father and you will no longer see Me; about judgment [the certainty of it], because the ruler of this world (Satan) has been judged and condemned.
