So you see the beheadings of the recent years as insignificant in the fulfillment of God's word?
No beheading is insignificant. But these now being beheaded and those a thousand years ago beheaded for their witness are not those beheaded during the Tribulation. Nero managed to make worse evil upon the faithful than just beheading them. He used to cover them in pitch and wrap them in animal skins soaked in fuel oil and set them on fire to light his parties. Is it any wonder Nero died suddenly when Vespasian and his brutal son Titus were at Jerusalem’s door?
