'Understand Endtime Scriptures'
Before Rapture, at the dedication of the so-called temple of God (seen by all via TV), the Antichrist or lawless one by deception will be found seated on the mercy seat where he will declare himself god. Almost everyone having accepted the mark of the beast or '666' will bow down and worship the Antichrist, except for the knowledgeable Christians and Israelites (foretold by dreams and visions)
*Note* God already has the physical body of every born-again Christian as His temple.
Rev 11:1-2 Then I was given a reed like a measuring rod. And the angel stood, saying, "Rise and measure the temple of God, the altar, and those who worship there. But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city underfoot for forty-two months."
At Rapture the Antichrist will be killed by the coming of our Lord. John's mission is to keep his followers from entering the temple to worship the Antichrist (dead)
Rev 11:3-4 "And I will give power to my two witnesses, and they will prophesy one thousand two hundred and sixty days, clothed in sackcloth." These are the two olive trees and the two lampstands standing before the God of the earth.
John will be coming back as one of the two witnesses for 1,260 days.
Mark 10:37 They said to Him, "Grant us that we may sit, one on Your right hand and the other on Your left, in Your glory."
The Beloved Apostle John
1. The only Apostle present at His crucifixion (John 19:26)
2. Jesus trusted him to look after Mary, His mother (John 19:27)
3. The only Apostle who believed His resurrection, without having seen Him. (John 20:8)
4. He was frequently referred to as the one 'whom Jesus loved'.
John 14:21 "He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him."
When Jesus manifests in the two witnesses (including John), they will display His powers and authority, to execute the trumpets judgment as His wrath.
Rev 11:5-6 And if anyone wants to harm them, fire proceeds from their mouth and devours their enemies. And if anyone wants to harm them, he must be killed in this manner. These have power to shut heaven, so that no rain falls in the days of their prophecy; and they have power over waters to turn them to blood, and to strike the earth with all plagues, as often as they desire.
Rev 11:7 When they finish their testimony, the beast that ascends out of the bottomless pit will make war against them, overcome them, and kill them.
After the two witnesses have finished their missions (preaching the gospel, God's plan of their salvation, etc.) only then the devil dare to come out and kill them. They will resurrect and will be seen going up to heaven. John's mission is to evangelize and save the remnant Israelites in Jerusalem.
Rev 11:11-13 Now after the three-and-a-half days the breath of life from God entered them, and they stood on their feet, and great fear fell on those who saw them. And they heard a loud voice from heaven saying to them, "Come up here." And they ascended to heaven in a cloud, and their enemies saw them. In the same hour there was a great earthquake, and a tenth of the city fell. In the earthquake seven thousand people were killed, and the rest were afraid and gave glory to the God of heaven.
The Period of the Wrath of God is 1,260 days or 42 month.
