He would return to Judge the world
"And He ordered us to preach to the people, and solemnly to testify that this is the One who has been appointed by God as Judge of the living and the dead.
(Acts 10:42)because He has fixed a day in which He will judge the world in righteousness through a Man whom He has appointed, having furnished proof to all men by raising Him from the dead."
(Acts 17:31)on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.
(Romans 2:16)For we must all appear before the judgment seat of Christ, so that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad.
(2 Corinthians 5:10)I solemnly charge
you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom: (2 Timothy 4:1)And inasmuch as it is appointed for men to die once and after this
comes judgment, so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him. (Hebrews 9:27-28)And I saw the dead, the great and the small, standing before the throne, and books were opened; and another book was opened, which is
the book of life; and the dead were judged from the things which were written in the books, according to their deeds. And the sea gave up the dead which were in it, and death and Hades gave up the dead which were in them; and they were judged, every one of them(Revelation 20:12-15)
