“Parousia” is the New Testament word that means “return of the King”. It is used to describe the Last Day when Jesus will return as the King of all things. Jesus will return to judge the living and the dead; it will be visible, every eye will see Him, history will end, and the dead will rise. Believers will spend eternity in Heaven, unbelievers will be condemned to hell. When Jesus returns on the Last Day — at the Parousia — it will be judgement day for every single person ever conceived. The Parousia is the third and final “once and for all” event in earth history.
