"In my zeal and fiery wrath I declare that at that time there shall be a great earthquake in the land of Israel. 20 The fish in the sea, the birds in the sky, the beasts of the field, every creature that moves along the ground, and all the people on the face of the earth will tremble at my presence. The mountains will be overturned, the cliffs will crumble and every wall will fall to the ground. 21 I will summon a sword against Gog on all my mountains, declares the Sovereign Lord. Every man’s sword will be against his brother. 22 I will execute judgment on him with plague and bloodshed; I will pour down torrents of rain, hailstones and burning sulfur on him and on his troops and on the many nations with him. 23 And so I will show my greatness and my holiness, and I will make myself known in the sight of many nations. Then they will know that I am the Lord."
After that attack, it says there will be so many dead that it will take Israel seven months to bury them all.
Here is another that still needs to be fulfilled:
"This is the covenant I will make with the people of Israel after that time,” declares the Lord. “I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people. 34 No longer will they teach their neighbor, or say to one another, ‘Know the Lord,’ because they will all know me, from the least of them to the greatest,” declares the Lord" (Jeremiah 31)
And this one we have seen being fulfilled in this century and the last:
"However, the days are coming,” declares the Lord, “when it will no longer be said, ‘As surely as the Lord lives, who brought the Israelites up out of Egypt,’ 15 but it will be said, ‘As surely as the Lord lives, who brought the Israelites up out of the land of the north and out of all the countries where he had banished them.’ For I will restore them to the land I gave their ancestors"
“There are still numerous prophecies waiting to be fulfilled. Everything in Revelation for instance.”
Nope. Everything in Revelation has been fulfilled, right down to Vespasian’s legions encamped in the Valley of Meggido (Armageddon) on their southward march through Samaria to Jerusalem.
Christ’s kingdom is His church - which is His body - over which He is the head. If you are born again, congratulations! You’re already in His kingdom: a kingdom of heaven, not earth.
