Seven of this and Seven of that and Seven of some more. Just your thoughts. Revelation says that all of these calamities will be brought upon the Earth just before Jesus comes back. If I read all of the calamities right, most of the Earth is going to be wiped out. In the Bible, there is talk about Mystery Babylon the religion of the False Prophet. According to prophecy, this End Time Religion will be ensconced in North Africa, Eastern Africa, the nations all around Israel, the Turkish Republics (That have always acted absolutely crazy) and the Kings of the East (Iraq, Iran, Pakistan and parts of India). It is rather obvious to me who the False Prophet is and what his religion is, as only one religion is located in all of those countries. This end time religion will be cutting the heads off of Christians as it says in Revelation. Millions will be beheaded for their testimony of the Word of God. I suspect that all the trials and tribulations that the Earth receives will be directed at Radical Islam because it will set itself up as the enemy of God (JHVH).
