The following is a theme-study I did for a class at Biblical Seminary on the New Testament term parousia:
Jesus’ disciples pose an interesting question to Jesus, “Tell us, when will these things happen, and what will be the sign of Your coming [parousia], and of the end of the age” (Mt. 24:3 NAS)? Jesus speaks of his parousia as a monumental event. He states, “For just as the lightning comes from the east and flashes even to the west, so will the coming [parousia] of the Son of Man be” (v. 27), and “will be just like the days of Noah…they did not understand until the flood came and took them all away; so will the coming [parousia] of the Son of Man be” (vv. 37, 39).
