Daniel 2:31-35 “…its feet partly of iron and partly of clay.”

God revealed to Daniel the dream of King Nebuchadnezzar. The part of the dream that comes to mind the most is the feet.
There is much speculation about the kingdoms.
Daniel reveals the head of gold is Nebuchadnezzar’s kingdom followed by three more inferior kingdoms.
The last one contains legs of iron but feet mixed with iron and clay.
I’ve heard the final kingdom is a revived Roman empire, the Russian’s, or the Chinese.
I tend to think the final kingdom is an Islamic kingdom.
My reason for this is the rise of Islam.
Also the Muslim’s divide themselves as Sunni’s and Shiite’s.
Of course, I’m sure there are many other religions with divisions as apparent as iron and clay.
Spiritually speaking, you must decide how you stand in Christ. You cannot mix the clay of the world with the iron of the Lord.
What fellowship is there between light and darkness or righteousness and unrighteousness?
Don’t be mixed up! Choose you this day who you will serve!
