That makes no sense.
Do you mean that Jesus told us to hide inside the mountains, not just go up into the mountains?
Even then, there is thick soil and rock in other regions.
And lead is better than rock, so why didn't he tell us to build fallout shelters?
You can't outrun the blast radius of a nuclear weapon. If you are not already in a shelter when it starts, you are toast. Jesus should have told us to live underground in preparation. His advice is pretty useless.
Why is it called "The Sea Beast"? That doesn't really fit.
China is not in any position to launch an amphibious attack on Taiwan. They don't have the resources.
Hide in the mountains is hide in caves I assumed people would realize that to be under thick dirt then one is in a cave but glad you pointed that out because it is advantageous for people to know the closest cave in their area. Hide in rocks is go deep in a sheltered area of rocks/ concrete, for example, which is like a fallout shelter.
Houses/cities will be targets so sitting in a fallout shelter will not help a person in a direct hit because as the house is destroyed in a nuclear blast so will be the shelter.
Thermonuclear weapons are vastly more powerful than a puny atomic bomb. A "sea of burning glass" described in scripture is what happens to a desert city when hit by a thermonuclear missile. The city just evaporates with the heat, nothing left of it and the sand surrounding the huge pit left, melts and fills in the void creating a sea of glass so hot it still has flames flickering on it.
Fallout has a distinct radius in the beginning. True, if one is in the direct hit area life is gone so fast, the Bible calls it an "instant", that people won't even feel it. But if outside the blast people have about a half hour to get out and seek safety before where they were standing is saturated with unsurvivable fallout. Jesus said do not try to take your stuff with you before you flee and that is because time won't allow it. Jesus said do not go back for your stuff and that is because a radiated area can not be seen but to touch the stuff in it can kill you. What did have value is now completely worthless so leave it.
World War 3 is fought in 2 areas of the world for completely different reasons like WW2 was.
One area of WW3 is called the BEAST and that is fought over religion and ownership of the world. This part of WW3 is fought over differences in Abrahamic religions each sect /religion and there are 3 of them, Jews/ Muslims and Pauline Christians each believe their God has the plan that they will rule the world.after a great war. Abraham lied about establishing an eternal kingdom on Earth but they do not believe it because they refuse to believe Jesus Christ, Son of God that said Abraham lied.
The other part of WW3 is fought in the Pacific area like WW2 as Japan will be involved fighting against China this time. Nuclear war in the South China Sea called the SEA BEAST to show the difference between the cause of this part of combat from the reasons nuclear war, the BEAST, started in the middle east after Israel is attacked with a nuclear weapon.
China is the red dragon, dragon is their national symbol and red represents communism. This part of world war is fought over ownership of the South China Sea.
China's high hand is advanced computer code. And do not underestimate the amount of recent build up of their advanced technology and military.
They have even created a new island in the ocean just to put an airstrip on it as a military base.
China is going to attack Taiwan and the island nations in hopes to take their sovereign rights away and take their land and resources. This is going to be horrific combat as people will fight for their life and rights.. The sea has so much dead in it that it is said "a third of the sea becomes blood". The missile blasts do not just kill people it also kills sea life in the ocean creating massive loss of life .
