Oh, no doubt that Satan will indeed be the source of the Antichrist's power but Satan and the Antichrist are not the same person. Satan is a fallen angel and has no physical body - certainly not a human one. But demons CAN indwell people and animals. At the beginning of the Great Tribulation Satan will indwell (possess) the Antichrist becoming the source of his power. (Rev. 13:4 ) Then in Rev. 19:19-20 we read that the Antichrist and false prophet are captured and thrown into the Lake of Fire, while in Rev. 20:1-3 Satan is captured and confined for 1000 years. Two different beings - Antichrist and Satan.
You seemed to be saying that you knew WHO the Antichrist is right now. It will be a man who will rise to global power and take over. That human man, I believe, IS alive today and not as yet reveal. It may be closer than we think.
That 'mark of the beast' is taken willingly, because the children have not done their home work ... One ceases to be Christian when they worship a fake Jesus...
I do not know what the rapturites think the 'tribulation' that Christ said 'time' was shortened for the elects sake ... but according to Christ 'wars and rumors of wars' were not the end ... the opposite of wars and rumors of wars is 'peace', 'peace', 'peace'... No self respecting fake Jesus is going to be letting blood, rather they would be play acting like they were Jesus ... Do you love me? or as the devil tempted Christ to bend His knee...
Ezekiel 28 lays out Lucifer and his rebellion, and Satan was never called a 'fallen angel'... check out Jude.
There have been plenty of 'humans' in the flesh that have followed Satan, and still do, some in total complete ignorance.
