“And when he comes, he will prove the world wrong concerning sin and righteousness and judgment— concerning sin, because they do not believe in me; concerning righteousness, because I am going to the Father and you will see me no longer; and concerning judgment, because the ruler of this world has been condemned.”
These are the subjects of the Holy Spirit. He revealed the word of truth. Awareness of wrong is necessary to put one on the road to righteousness.
Jesus had to return to heaven in order for the Holy Spirit to come. We are blessed to have his truth in Scripture. How precious is that truth to me?
