"Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead." (Acts 17:30-31)

We learn from the above passage that the "time" for the judgment has already been set - "He has appointed a day." The "manner" in which He will judge is set - "He will judge the world in righteousness." The "Judge" has already been assigned - "He will judge the world by the Man whom He has ordained." The "assurance" of the judgment has been clearly established - "He has given assurance of this to all by raising Him from the dead."

Are you ready for that day to come?
