So I was thinking about the book of Revelation one day, and was thinking about how horrible it seemed like it would be. I was also thinking about the many times that it appeared God was declaring/commanding for an event to take place in the Bible, but that in those same instances, someone changed God's mind (Hezekiah, Moses, etc.). This made me wonder, can the prophesies in the Book of Revelation be changed/prevented? Are some of the things God said would happen really God's will for that time? Or could God be moved like Hezekiah moved him, so that what was planned could be prevented? One thing I would really like to see is that the Anti-Christ not be allowed to overpower believers in the end-times. I mean, really, how could that be God's will? "Yes, that's right my angels, I want people to be deceived by a powerful looking devil who appears to be trumping me at every corner." That's something that I can't stomach as God's will, and so I would think that if people pursued it enough, that it very well could be changed. But for information's sake, let's look at the passages where at least Hezekiah and Moses changed God's mind.
2 Kings 20:1
"1 In those days Hezekiah became ill and was at the point of death. The prophet Isaiah son of Amoz went to him and said, "This is what the LORD says: Put your house in order, because you are going to die; you will not recover."
This is a command of the Lord. So if the Lord is always right, and what He says will happen will happen, then shouldn't Hezekiah simply have said "Okay, Lord" ? But maybe God doesn't want us to be just robots always simply obeying every word he says. Below is what Hezekiah does, and God's response to it:
2 Kings 20:2,3
"2 Hezekiah turned his face to the wall and prayed to the LORD, ...And Hezekiah wept bitterly."
2 Kings 20: 4,5,6
"... 4 Before Isaiah had left the middle court, the word of the LORD came to him: 5 "Go back and tell Hezekiah, the leader of my people, 'This is what the LORD, the God of your father David, says: I have heard your prayer and seen your tears; I will heal you. ...6 I will add fifteen years to your life. And I will deliver you and this city from the hand of the king of Assyria."
So we see, the fabric of destiny was changed, as was the decision of the Lord, because Hezekiah chose to do something.
As for Moses' situation:
Exodus 32:8, 9-10
" 8 They have been quick to turn away from what I commanded them and have made themselves an idol cast in the shape of a calf. ...9 "I have seen these people," the LORD said to Moses, "and they are a stiff-necked people. 10 Now leave me alone so that my anger may burn against them and that I may destroy them. Then I will make you into a great nation."
Again God gives Moses a command, but instead of simply obeying, Moses talks to God about it:
Exodus 32:11,13
"11 But Moses sought the favor of the LORD his God. "O LORD, ...13 Remember your servants Abraham, Isaac and Israel, to whom you swore by your own self: 'I will make your descendants as numerous as the stars in the sky and I will give your descendants all this land I promised them"
And God's response:
Exodus 32:14
"14 Then the LORD relented and did not bring on his people the disaster he had threatened."
So here are two passages in the Bible that say that God's word isn't always a final word. We know from the story of David's sin with Bathsheba, that sometimes God's word is a final word, as God told David that the child Bathsheba had first born to him would die, and it did (2 Samuel 12). But who says the book of Revelation all has to be final? We know that God has at least two wills- the one he doesn't want to carry out but has to because he is a just judge (Ezekiel 22:30), and the one that he wanted to always carry out to begin with in his loving heart; so why couldn't the events in Revelation that certainly don't look like the perfect will of God be changed? Maybe they can. (And Jesus told his disciples to pray that the Day of the Lord would not take place in winter- Matthew 24:20)
