Good day Jackson123!
Yes, the word "ek" in the original is defined as "out of" as in, "I will keep you out of the hour of trial that is coming upon the whole world."
Below is the scripture:
"Because you have kept the word of My patient endurance, I also will keep you out of the hour of the trial being about to come upon the whole inhabited world, to try those dwelling upon the earth. "
Notice that the Lord said that this time of trial is going to come upon the whole inhabited world. This "hour of trial" is another description for "the day of the Lord" i.e. the time of God's wrath, which is described in detail from Revelation chapters 6 thru 18 and which will take place via the seals, trumpets and bowl judgments. This is how God is going to carry out that time of trial/tribulation, which will be through his coming wrath.
Yes, I believe that those who become believers during that time will flee from, not only from the beasts persecution, but will also be exposed to the seals, trumpets and bowl judgments and that because they will be on the earth during that time.
You have to keep in mind that the church is never referred to again after the end of chapter 3. And there is a reason for that. It is not a coincidence that the word church is used throughout chapters 1 thru 3 and then never used again. The word changes to "saints" and the word "church" no longer appears in the narrative. If these two words were used interchangeably throughout Revelation then it would not be an issue. It is the segregation of the two words that demonstrates a change from Revelation 4 onwards. The saints referred to beginning in Rev.5:8 is in reference to the great tribulation saint, who is not the church, but are those who will believe in Christ after the church has been gathered and during the time of God's wrath and the beasts reign.
I hope this sheds some light on the subject.
Regarding #1, the church will not be persecuted by Satan during the last 7 years and that because the church will be gathered prior to the 1st seal being opened.
Regarding #2, Yes, the seals, along with the trumpets and bowl judgments all make up God's wrath, including the plagues that the two witnesses bring upon the earth during that time. You have to remember that it is Jesus who is opening the seals, not Satan or mankind. Jesus is the One who will be trampling the wine-press of the wrath of God Almighty and he will accomplish this through the seals, trumpets and bowl judgments.
That last seven years will be the fulfillment of the seventy seven year periods that was decreed upon Israel as revealed in Dan.9:24. The seven years begins when that ruler, the antichrist, establishes his covenant with Israel for one seven year period. Therefore, it is not the wrath of Satan or man, but the time of God's vengeance, the day of the Lord, the time of God's wrath.
During that same time period God's wrath will also be poured out upon a Christ rejecting world via the same seals, trumpets and bowl judgments. This is what is in view regarding Dan.2:31-45. The statue represents world government with the ten-toed kingdom made of partly iron and partly baked clay being the last kingdom, which the antichrist will rule over. The Rock, which is symbolic for Christ, falls on the feet off the statue smashing it to pieces like chaff on a threshing floor, with the wind blowing it away without leaving a trace, which represents the end of all human government never to be reestablished. Then, the Rock/Christ becomes a huge mountain and fills the whole earth, which represents Christ's millennial kingdom.
