How do we know that Jesus will judge all people?

Scripture assures us of the reality of Christ's judgment over humanity, highlighting that He is appointed to this significant role by God. Acts 17:31 proclaims, 'He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained.' This speaks to the authority and the inevitable reality of His judgment, as it is established by divine decree. Furthermore, Hebrews 9:27 affirms that it is appointed for man to die once, and after that comes judgment, reinforcing the necessity of every individual standing before Christ’s judgment seat.
