In this verse John looks forward to the second coming of Jesus Christ. It is important not to confuse the second coming with the rapture. The rapture occurs when Jesus comes in the sky and catches up Christians from the earth to be with Him. The rapture is a secret event, in the sense that only those who are saved will see Jesus. On the other hand, the second coming is a public event. John declares that every eye will see Jesus at the second coming.
Also, the tribes of Israel will have undergone a national revival when Jesus comes again. There is no mention of such a revival before the rapture. John recalls what Zechariah had prophesied about Israel’s revival when Jesus comes to earth again. Zechariah 12:10 prophesies, “And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and pleas for mercy, so that, when they look on me, on him whom they have pierced, they shall mourn for Him, as one mourns for an only child, and weep bitterly over him, as one weeps over a firstborn.” Likely, John remembers what the angel told him and the other apostles when Jesus ascended into heaven. The angel promised that Jesus would come again in the same way as He went into heaven. Then, Jesus ascended in a cloud from the Mount of Olives (Acts 1:11–12), and at His second coming He will return in the clouds to the Mount of Olives (Zechariah 14:4; Matthew 24:29–30).
John’s joyful anticipation of Jesus’ return to earth caused him to exclaim, “Even so. Amen” (Revelation 1:7). We, too, should eagerly anticipate the second coming, because Jesus will reign over the earth, and we will reign with Him (2 Timothy 2:12).
Revelation 1:4–8 identifies John’s audience as the seven churches in Asia. John addresses these churches with a greeting from the triune God, and he ascribes praise to Jesus. Jesus is coming in glory, John declares, and His coming will be visible to everyone. At that time, the tribes of Israel will express remorse because of His crucifixion. John concludes this passage by quoting Jesus as saying He is the beginning, the eternal Almighty One.
The Roman government had banished John to the island of Patmos in the Aegean Sea, off the coast of Asia Minor, modern-day Turkey. While John was at Patmos, the risen, glorified Son of God appeared to him and commanded him to write ”the things that you have seen, those that are and those that are to take place after this” (Revelation 1:19). John pronounces blessings to those who read and obey Revelation, and then he greets his readers warmly and describes Jesus’ appearance.
