Puzzled About Revelation: Part 21: The Name and Number of the Beast (Rev. 13:16-18)

This week: What is the "mark of the Beast"? What is the name and number of the Beast? What is the significance of 666? How does understanding biblical creation and the Gospel help us to understand biblical prophecy in this area? How are all these things connected to the WEF's Great Reset and 4th Industrial Revolution (Transhumanism)?
The Bible says that those who refuse to worship the image and receive the mark will be killed, and those who do worship the image and receive the mark will suffer eternal death. Clearly, this IS a Gospel-issue and matter of eternal significance! Why would God allow this? How can we be overcomers?
