I believe you would have to be in Judea.
Luke 21:21 Then let then which are in Judea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.
Everyone goes to the mountains in the Tribulation after the sixth seal is opened.
Revelation 6:15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every freeman, hid themselves in the dens and in the rocks of the mountains;
I plan to follow the Bible step by step if the tribulation happens when I am alive. I do not see the need to flee unless you are in Judea. I believe even Christians will go with the rest of the World to the mountains after the sixth seal is opened. People move to the mountains for safety. The sixth seal even moves mountains. Revelation 6:14 "And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their place." When the sixth seal is opened there is a great earthquake and the earth is changed. People move into the mountains.
It would be easier in the tribulation to make it if you had the Bible. They might start taking Bibles away under the leadership of the Beast. I would try to hide Bibles. I also consider when Christians are not allowed to buy or sale because they do not have the mark of the Beast. We should trust in God and not take the mark of the Beast. Once you have taken the mark of the Beast you are destind for Hell with no chance to repent.
I do not believe that Christians will suffer the wrath of God. Much of the tribulation is God's wrath on the World. But I do believe we will be persucuted by the Beast and the World; not all of the Tribulation is God's wrath, some of the things in the Tribulation are from the Devil.
