The use of a computer chip "in the right hand" and "in the forehead" as some expect is in fact not very likely at all, no matter if you're a preterist or not.
The chips need to be injected into a rather fleshy area like the thigh or upper arm. Special Forces troops that have radio locator responders implanted almost universally have them in their thighs. A few opt for the upper arm/shoulder area because of the belief that they'll get marginally better radio reception. And, the chips move around and tend to migrate up to the surface of the skin - like an old splinter. People will be scratching the things out in their sleep.
Can you imagine having anything implated in your forehead or the back of your hand (as
Revelation 13 seems to suggest). This idea gets promoted a
lot. On that site they've photoshopped a "chip" into a jpg of an x-ray of a human hand. No doctor would suggest such a sight for such an implant.
This just doesn't pass the feasibility test with me. It seems that something else was in mind as far as "the mark" is concerned (compare, for example,
Deuteronomy 6:1-8), like maybe obedience to His word. In the case of
Rev. 13, it would be disobedience to God's word and a willful complicity with the commands of the adversary.
Is God going to have angels implant microchips into the foreheads of the 144,000? (
Revelation 7). No one ever preaches
that. Yet to be consistent - if a "mark" must be an injected chip in
Rev. 13, then "mark" must also be understood as an injected chip in
Rev. 7.
If so, will there be some sort of Intel/AMD type of battle that has to be fought out before the time of the end? What if the angels (or even The Beast) have moved beyond the X86 architecture but the majority of humanity has failed to upgrade? Will there be some sort of firmware download that will make everyone compliant?
No, I believe God (and even the devil) has something in mind that will not even remotely resemble the evil of today's computer and electronics industry. And that is a blessed hope.
