The reason I gave you all of the passages together was to show you that they are all saying the same thing, that Christians resist worshiping the Beast by not accepting his mark. This leads to their martyrdom.
That is a reasonable assumption.
It is the wrong presupposition added into God's Word.
When the mark is handed out by God, it is after the Second Coming. After the final harvest gathered by Jesus and the angels. This 42 month period is after the 7th Trumpet has already sounded, and Jesus was made King over all nations as the 7th one world kingdom.
Revelation 13 comes after Revelation 11:15.
There are no Christians on the earth after the 6th Seal. No one becomes a Christian during the Trumpets and Thunders. During the final harvest souls are removed from the earth and placed in the LOF or are waiting on the sea of glass. No one is hiding out somewhere on the earth.
The sea of glass: Revelation 4:6
"And before the throne there was a sea of glass like unto crystal:"
"And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God."
These people are not hiding out on the earth. They are gathered on this sea of glass having the victory over what is going on down below. But they have a body, and are not standing in judgment, nor waiting to be beheaded.
Those beheaded are judged after the 42 months and after Satan is bound. The beheaded are not waiting on the sea of glass.
Comparing those on the sea of glass to the harvest of Matthew 13 and the judgment of the sheep in Matthew 25, they were already judged and given eternal life, the first resurrection. They were waiting in heaven on this sea of glass way before the 7th Trumpet even sounded. They had the victory over the beast and his image, because they were already redeemed and waiting for the 7th Trumpet to sound.
Those beheaded are the redeemed during the 42 months. But their redemption was in the form of chopping their head off, and then waiting to be judged later after Satan was bound. They were given the first resurrection after Satan was bound. Those waiting on the sea of glass would be those returning on white horses to the battle of Armageddon. The victory already assured.
John never writes about a survivalist group hanging out on the earth somewhere who never physically left their corruptible bodies behind. Not even in Revelation 12.
"And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days."
"And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent."
This is the symbolic preservation of Israel still pure without becoming corrupt by the work of world government and Satan. This is in comparison to the harlot that Israel plays as Jerusalem, given to the governmental authority of Satan. But the remnant of faithful Israel are waiting on the sea of glass, redeemed, not hiding out on the earth.
"And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ."
These would be those beheaded. The only reason that Satan is given 42 months is if God in His foreknowledge knows there will be at least 1 beheaded person. But the moment of their redemption from their dead corruptible flesh is when they chop their head off. That is their testimony of Jesus Christ and in keeping of the commands of God. Especially during a time when this is true: Daniel 9:27
"and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate."
Even the alter call of redemption is the abominable act of chopping one's head off. There is no sacrifice nor oblation of sin. One cannot accept by faith and continue to live in sin (become a Christian). They have to be removed from this body of flesh. That is the purpose of being beheaded, not that they were martyred for being a Christian. Those still in their physical body are marked by God, and their names removed from the Lamb's book of life. The final harvest is about leaving corruption behind, not to see how long one can avoid the mark.
"And the dragon was wroth with the woman, and went to make war with the remnant of her seed"
When people read this they conjure up an actual conflict like the Spanish Inquisition or the Reformation where Satan beheads heretics. Then they read:
"And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations."
Same authority as the other verse, so instantly it means to many they were all killed. Except they were not dead. They were waiting on Mount Zion with Jesus. Satan did not kill Jesus nor the 144k. The authority was given to Satan by Jesus.
"And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads."
Satan is the 8th King of the 8th Kingdom. Satan did not kill Jesus to gain the throne. God granted Satan 42 months of authority for the only reason being; some humans would choose to be beheaded instead of follow Satan's authority.
Otherwise Jesus would not give up the throne and the Millennium would start with Satan being bound for a thousand years, and no 42 months of the 8th kingdom would ever happen. There would be no 3rd woe, nor the 7 vials poured out. Not even a battle of Armageddon nor the mark. The harvest would be complete at the 7th Trumpet. Any one left would be killed and placed into Death to await the GWT Judgment.
