The Mark of the Beast is often misunderstood as a physical mark (or chip) placed on people, during the time antichrist is on earth, for those who worship antichrist and his system. However, that is an assumption based on misunderstanding of scripture.
The Mark of the Beast will be dealt to most of the people on earth (Mat 24:24, Rev 7:3-4, 12:9-15, 13:11-16) while antichrist is here because they will have been deceived into worshiping him and his system (Rev 14:9), and they will have served him because they will believe he is the Messiah. This mark is not a physical mark because it is based on what people feel in their hearts; and therefore it goes much deeper than a physical trait. No one can hold us down and force us to feel something in our hearts and therefore a physical mark cannot change our minds. God cares more about where our loyalties lie, than what someone has made us do to ourselves physically.
This mark is in one’s forehead and in one’s right hand (Rev 13:16), and these terms are symbolic. The mark that is in people’s foreheads is in their brains, and it is those people’s belief that antichrist is the Messiah or God, which he will claim to be. This is the mark of deception that is brought forth in the flood of lies from satan’s mouth (Rev 12:15). The mark in the right hand represents someone’s works in serving the system of antichrist, and doing his will. The right hand in biblical times was always symbolic of power or work.
The Mark of the Beast is mutually exclusive with the Seal of God, meaning that everyone on earth will have either the mark or the seal. The Seal of God is protection against the torment that those with the Mark of the Beast will suffer (Rev 7:3, 9:1-11, 14:9-11,16:1-4, 8-14, 17-21). Those with the Mark of the Beast will continue to be plagued through the tribulation unless they wake up and repent, and turn against antichrist (Mar 3:28-29, Luk 21-12-19, 1Jo 1:9, Rev 16:1-4, 8-14, 17-21) before Jesus returns.
Those without the Mark of the Beast will not be allowed to buy or sell (Rev 13:17), and that can be accomplished by many ways even though the mark is not a physical mark. One such way as there may be a card issued to those who have proven their loyalty to antichrist when they have worshipped him, but that card would not be the mark. God’s people will be provided-for none-the-less because they will remain faithful to Jesus Christ and not fall for antichrist.
The only way to avoid receiving the Mark of the Beast is to read, study, and understand the Bible (2Th 7-12, 2Ti 2:15, Rev 7:1-4), as even many professing Christians will be deceived, along with the rest of the world (Mat 24:22-24, Mar 13:20-23, Rev 12:9-15, 13:11-14), because they don’t care enough for Jesus to pick up God’s Word and read it. Those people who will be sealed by the Holy Spirit as protection are those who know and love Jesus Christ and His Word (2Ti 2:15, Rev 7:3-4), as He is the Living Word, and this sealing will be accomplished before antichrist arrives (Rev 7, 9:1-12).
The receiving of the Mark of the Beast does not condemn someone to die in the Lake of Fire, however, they will be in danger of this sentence (Rev 20:4-6, 11-15) if they do not repent and turn back to and serve Jesus Christ once they realize what they have done. Those who do not do so by the time Jesus Christ returns will have a chance in the Millennium Kingdom to be taught and disciplined to learn the ways of God and forsake their selfish ways (Eze 44, Rev 20:1-6). During this time, they will be considered spiritually dead (Eze 44:23:25, Rev 20:4-6, 12-13), and at the end of the Millennium, they will be tested one last time (Rev 20:7-9), and if they fail this test, after the Great White Throne Judgment, they will be thrown into the Lake of Fire (Rev 20:11-15). If they instead pass and are found in the Book of Life, they will be granted eternal life at that time (Rev 20:5, 21, 22).
If someone is truly saved by Jesus Christ, though they may be deceived when antichrist is here, they will overcome in the Millennium, or perhaps before, because they love Jesus Christ and they will do what it takes to make it right (Rom 1:16, 11:23-27, 1Ti 2:10). The only way to salvation is to accept it through Jesus Christ (Joh 14:6-7, 1Th 5:9, 1Ti 2:10, 3:15), and our lives will reflect that salvation if we are truly saved (Tit 2:7-15, 3:1-8, 14-15, Jam 2:14-26, Rev 2:4-5, 20:11-13).
