Why is Islam sweeping the world?

Because you wanted it.  You demanded it.

(Hint: your gods of modesty/sexism/objectification/exploitation.)

Revelation 22:11
   He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still

God acts very consistently.

Hebrews 13:8
   Jesus Christ the same yesterday, and to day, and for ever.

Let’s see how God consistently amplifies the unjust.

The Egyptian Pharaoh had no love for his slave labour – the Israelites.

Exodus 1:13-14
   And the Egyptians made the children of Israel to serve with rigour:
   And they made their lives bitter with hard bondage, in morter, and in brick, and in all manner of service in the field: all their service, wherein they made them serve, was with rigour.

And, of course, the Pharaoh denied God’s request for Israel’s feast.

Exodus 5:1-2
   And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the LORD God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.
   And Pharaoh said, Who is the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go.

Since Pharaoh had made his decision regarding his attitude toward the Israelites, God amplified this decision, by hardening Pharaoh’s heart.

Exodus 7:13
   And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said.

Exodus 9:12
   And the LORD hardened the heart of Pharaoh, and he hearkened not unto them; as the LORD had spoken unto Moses.

Exodus 10:27
   But the LORD hardened Pharaoh's heart, and he would not let them go.

Later in years, when the Israelites turned back to worship false gods (such as those of Babylon), God amplified their decision by sending them to Babylon and its idols for seventy years (before breaking Babylon).

Jeremiah 25:6-9,11
   And go not after other gods to serve them, and to worship them, and provoke me not to anger with the works of your hands; and I will do you no hurt.
   Yet ye have not hearkened unto me, saith the Lord; that ye might provoke me to anger with the works of your hands to your own hurt.
   Therefore thus saith the Lord of hosts; Because ye have not heard my words,
   Behold, I will send and take all the families of the north, saith the Lord, and Nebuchadrezzar the king of Babylon, my servant, and will bring them against this land…
   ...and these nations shall serve the king of Babylon seventy years.

Isaiah 21:9
   Babylon is fallen, is fallen; and all the graven images of her gods he hath broken unto the ground.

Similarly, God will amplify the decision of those who choose to ignore the truth, and believe lies.

2 Thessalonians 2:9-12
   Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
   And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
   And for this cause God shall send them strong delusion, that they should believe a lie:
   That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

Key to the feminist religion is that women have superior morals compared to men.

A common instantiation of this moral superiority is the notion that men will become sexually vile if they see scantily clad or nude women.

Women seeing undressed men is tolerable, but, throughout the world, people from all walks of life (professing Christians, left-wing, right-wing, false religions, atheists, secular, etc.) can virtually all agree that women and girls must be covered up in the face of the male gaze.

Terms like ‘sexist’, ‘objectification’ and ‘exploitation’ reappear in secular discussions regarding images of women who are not fully dressed.

And, professing Christians, in agreement with the worldwide religion of feminism, have twisted Biblical verses to create a religion of hiding females from the male gaze.

‘Modesty’ has changed from avoiding expensive, decadent outfits, jewelry and hairstyles to simply covering up.

1 Timothy 2:9
   …women adorn themselves in modest apparel, with shamefacedness and sobriety; not with broided hair, or gold, or pearls, or costly array;

If she belongs to another man, men are not to desire to steal another man’s property.  But this has nothing to do with nudity.

Matthew 5:28
    whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.

Job 31:1
   I made a covenant with mine eyes; why then should I think upon a maid?

Since the world, including professing Christians, has decided that they love this feminist religion of covering women up, God has amplified this decision by giving the world Islam, and having it aggressively spread around the world.

Islam is a formal religion which covers women up with burkas and keeps women out of sight by restricting women’s movement.

Sexist!  Misogynist!  Objectification!  Oppression!
