The Horseman on the Red Horse of the Book of Revelation is Islam.
Every spirit that does not confess that Jesus came in the flesh is not from God and is the spirit of Antichrist that you have heard would come (which is already in the world). 1 John 4:3
When the second seal was opened I heard the second living creature say, “Come and see.” And there went out a second horse that was red. And power and a large sword was given to the horseman to take peace from the earth so that people would slaughter one another. Revelation 6:3-4
Adherents to Islam are divided into two denominations (and numerous sects). The two denominations can be described as moderate and radical.
The moderates follow the earlier, more peaceful writings in the Koran. Their part in conquering for Islam is to infiltrate and destroy other cultures by propagation and pressuring for support, accommodations, privileges and protection for their ‘peaceful’ religion.
Those who are termed radical follow the latter writings of conquest, murder, rape and mayhem in the name of the false god allah. They are the true fundamentalists, because it is specified in the Koran that the latter writings supersede the former.
Changing from moderate to fundamental, radical Islam is similar to and as easy as changing one’s denomination in Christianity. In either case Islam is Antichrist. Via S-S.org
