Peter cited how the Old Testament prophets sought to know what "time the Spirit of Christ within them was indicating the sufferings of Christ and the glories to follow" (1Pe 1:11). Jude reports "that Enoch . . . prophesied, saying, 'Behold, the Lord came with many thousands of His holy ones'" (Ju 10:14). Zechariah prophesied that "'the Lord will go forth and fight against those nations'" (Zec 14:3) and "'you will flee . . . [and] the Lord, my God, will come, and all the holy ones with Him!'" (:5). These are those who "God will bring with Him" (1Th 4:14) who "will be caught up together" (:17) in "our gathering together to Him" (2Th 2:1). "Creation waits eagerly for the revealing of the Sons of God" (Ro 8:19) and "the glory that is to be revealed in us" (:18). This revelation is an unveiling or exposure to view. We are to "wait for His Son from heaven" (1Th 1:10). Knowing that "our citizenship is in heaven" (Php 3:20) we set our "mind on the things above" (Col 3:2) and when Christ is revealed "you also will be revealed with Him in glory (:4). Paul prayed that God would "establish your hearts without blame in holiness . . . at the coming of our Lord Jesus with all His saints" (1Th 3:13). Peter prayed that your faith "may be found to result in praise and glory and honor at the revelation of Jesus Christ" (1Pe 1:7). Paul prayed "that you are not lacking in any gift, awaiting eagerly the revelation of our Lord Jesus Christ" (1Co 1:7).
The event of the Second Advent is called the parousia. Jesus, whose presence is in heaven, comes to earth where his arrival is observed by everyone. When it occurs is not known but there are metaphors to describe it. "'Just as the lightning comes from the east and flashes even to the west, so will the coming of the Son of Man be'" (Mt 24:27). It "'will be just like the days of Noah'" (:37). "'They did not understand until the flood came and took them all away'" (:39). "'On the day that Lot went out from Sodom it rained fire and brimstone from heaven and destroyed them all. It will be just the same on the day that the Son of Man is revealed'" (Lk 17:29-30). "'The powers of the heavens will be shaken. Then they will see the Son of Man coming in a cloud with power and great glory'" (21:26-27). He will come "with His mighty angels in flaming fire" (2Th 1:7) "'and then He will send forth the angels, and will gather together His elect from the four winds'" (Mk 13:27). Therefore "'when these things begin to take place, straighten up and lift up your heads, because your redemption is drawing near'" (Lk 21:28). "'What will a man give in exchange for his soul?'" (Mt 16:26). "'All the tribes of the earth will mourn'" (24:30). He "will both bring to light the things hidden in the darkness and disclose the motives of men's hearts" (1Co 4:5). "Each man's praise will come to him from God" (:5). Paul explains that he will receive "the crown of righteousness which the Lord, the righteous Judge, will award to me on that day; and not only to me, but also to all who have loved His appearing" (2Ti 4:8). He "will repay every man according to his deeds'" (Mt 16:27). He "rescues us from the wrath to come" (1Th 1:10). "'Then He will sit on His glorious throne'" (Mt 25:31).
