For as the lightning comes from the east and shines as far as the west, so will be the coming of the Son of Man.  (Matthew 24:27)

Jesus is speaking to four of his disciples telling them of what to expect in the end times and specifically, the signs of his second coming. The Greek word that translates the participle of the verb ‘to come’ is actually a noun παρουσία parousia; while this word has a common meaning, as here in Paul:

…God, who comforts the downcast, comforted us by the coming (parousia) of Titus…(2 Corinthians 7:6)

Actually, Jesus is referring the Parousia, the event of his glorious and triumphal return, where none will doubt his complete splendour and power; therefore, Jesus invokes the second and specific meaning of this Greek word, where the arrival of a King during a royal progression through his realm would bring his regal presence.
