WHEN DOES SATAN'S FORTY-TWO MONTH "HOUR OF TEMPTATION" ON EARTH BEGIN ?
The way to determine when Satan's forty-two month "hour of temptation" begins on earth is to first determine when it ends, and then calculate the beginning from the end. Jesus ends Satan's forty-two month "hour of temptation" on earth at His Second Coming to earth according to :
2 Thessalonians 2:8
"....whom the Lord will consume with the breath of His mouth, and destroy with the brightness of His Coming."
Therefore the forty-two months of Satan's "hour of Temptation" on earth immediately precedes the Lord's Second Coming.
We know the Lord completely and perfectly fulfilled the prophecies of God's three Spring Feasts of the Lord of Passover, Feast of Unleavened Bread, and the Feast of Firstfruits which is Resurrection Sunday. The Feast of Weeks, which is Pentecost, was perfectly fulfilled when God sent the Holy spirit into the world to begin the Gentile Church Age.
That leaves the three Fall Feasts of the Lord yet to be fulfilled; that is the Feast of Trumpets, the Day of Atonement, and the Feast of Tabernacles. The first is the Feast of Trumpets which always fall on the New Moon of Tishri 1, according to the Book of Leviticus. Tishri is always the seventh month on God's Sacred Calendar, and Nisan is always the first month on God's Sacred Calendar according to Scripture.
Therefore forty-two months prior to the seventh month of Tishri is the first month of Nisan, AND THERE YOU HAVE THE ANSWER !
Satan is CAST OUT heaven immediately prior to the Church being RAPTURED to heaven in the first month of Nisan ! ( Rev 12:10-12 )
