This passage presents the Triune God—Father, Son, and Holy Spirit—in perfect harmony. Jesus, knowing that He is going to the Father, in empathy for His followers, tells them it is to their advantage that He is going away, because the Holy Spirit will be sent to them. And the working of the Spirit is one of convicting or conviction, proving the truth about what is reality. Jesus defines three ways in which Holy Spirit conviction is directed: regarding sin, righteousness, and judgment. The Holy Spirit convicts people of sin who do not believe in Him. Then righteousness because He goes to the Father, and judgment because the ruler of the world, that is Satan, is judged and condemned. These things are not easily grasped nor understood. Also the Holy Spirit will teach them all things, bringing to their remembrance those things He has spoken to them prior.
