What part does Jesus have in the end of the world?
“God now commands all people everywhere to repent, because He has set a day on which He is going to judge the world in righteousness by the Man He has appointed. He has provided proof of this to everyone by raising Him from the dead.”
— Acts 17:30-31
He will return in power and glory to judge the world.
