According to my BibleWorks 10 software, the word Kingdom appears around 113 times throughout the Gospels:
c. 50 times in Matthew;
c. 40 times in Luke;
c. 20 times in Mark;
3 times in John 3.3, 5 you must be born again to enter the KOG;
John 18.36, my kingdom not of this world.
The coming of the Kingdom will be:
like a fast falling rock, crushing all other wicked kingdoms, Dan. 2:35, 44;
like a fast moving fire that will consume and bring to a sudden end all evil on earth, Zeph 1.18;
like the fast flash of lightning across the sky, Luke 17:23–24;
like the rush of the flood waters of Noah’s day, Luke 17:20–28;
like the sudden fire and brimstone of Sodom and Gomorrah, Luke 17:29–33;
As a result, unbelievers will be caught off guard and the wicked speedily judged (1Thess 5:3).
