On earth there will be a 7-year time known as the tribulation, in which the Antichrist (the beast or the lawless one) will first sign a peace covenant with Israël for seven years (Dan. 9:27). Half-way that time of seven years Antichist will break the covenant. The following 3.5 years of the tribulation on earth is called "the great tribulation" (Revelation 7:14) or "the time of Jacob's trouble" (Jeremiah 30:7) foremost focused on Israël. Antichrist (1 John 2:18) will set up an image of himself (the abomination of desolation) to be worshipped in the Jerusalem temple (Dan. 9:27; 2 Thes. 2:3-10), which has been rebuilt by then. At the end of the 7-year tribulation on earth, Antichrist will launch a final attach on Jerusalem, culminating in the battle of Armageddon (Revelation 16:16; 20:1-3). At this point in time Jesus Christ will return to earth, also called the second coming (Revelation 19:11-16), with His armies, and cast Antichrist along with his false prophet and his armies into the lake of fire. Jesus Christ will then bind Satan in the Abyss (hell, bottomless pit) for 1000 years. Jesus will judge the nations as King of kings and Lord of Lords (Revelation 19:11-16) regarding their position and acts towards Israël (Matthew 25:31-46, see also judgments). Then Jesus will rule His earthly kingdom for 1000 years, also called the millennium (Revelation 20:1-6). At the end of the thousand years Satan will be released for a short time and defeated again, and cast into the lake of fire (Revelation 20:7-10) for eternity. Christ then judges all unbelievers (Revelation 20:10-15, see also judgments) at the great white throne judgment, casting them all into the lake of fire. Christ will then usher in a new heaven and new earth (Revelation 21:1-8); there will be no more sin, sorrow, nor death. And the New Jerusalem comes down from God, the eternal dwelling place of believers (Revelation 21:9-27). There is no temple in the city, because the Lord God and the Lamb are its temple.
As we look at Revelation, we see that it seems to be all prophecy. In chapters 2 and 3 we see warnings, praises and encouragements to seven churches: Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia, and Laodicea (Rev. 1:11). The names of the churches are the names of real churches in Jesus' time. The chapters are part of the Revelation-prophecy. Some scholars think that the messages to these churches are just a report of history. I personally believe that the messages also have a prophetic content that is applicable to us today, when we prepare ourselves for the events to come; just because Rev. 1:19 speaks of "what is now and what will take place later".
