Revelation 13:15 And he had power to give life unto the image of the beast, that the image of the beast should both speak, and cause that as many as would not worship the image of the beast should be killed. 16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
The mark of the beast is not a one time thing. The beast system runs the world and we're all in it.
Revelation 14:1 And I looked, and, lo, a Lamb stood on the mount Sion, and with him an hundred forty and four thousand, having his Father's name written in their foreheads.
144,000 is 12 x 12 x 1000, it is a symbol of perfect government. The 144,000 are governed by the Father, they have disguarded the beasts economy, they don't bend to the beasts way of business.
It is shocking to think that it is either one or the other, it's either the beast or the Father.
Jesus Christ makes all things new(virgin), the 144,000 are virgins, this is a spiritual concept.
Revelation 14:4 These are they which were not defiled with women; for they are virgins. These are they which follow the Lamb whithersoever he goeth. These were redeemed from among men, being the firstfruits unto God and to the Lamb.
In order to defeat the mark of the beast you "follow the Lamb withersoever he goeth".
Revelation 15:2 And I saw as it were a sea of glass mingled with fire: and them that had gotten the victory over the beast, and over his image, and over his mark, and over the number of his name, stand on the sea of glass, having the harps of God.
The sea of glass mingled with fire is peace, when you've gotten the victory over the mark, you become new, a virgin, and the peace of God rules you.
"Throughout the scriptures the sea is a type of the inner storms and turbulent nature of the Adamic man. The prophet Isaiah penned these inspired words: “Thewicked are like the troubled sea, which cannot rest, whose waters cast up mire and dirt. There is no peace, saith my God, to the wicked” (Isa. 57:20-21). Jude also described wicked men when he said, “These are raging waves of the sea, foaming out their shame” (Jude 13). The beloved John on the isle of Patmos, had a vision of a great whore sitting on many waters. The angel revealed the meaning of the many waters, saying, “the waters which thou sawest, where the whore sitteth, are peoples, and multitudes, and nations, and tongues” (Rev. 17:15). I think there could be no better symbol by which to represent the people and society of any day than by the waters of the sea. At times the human race is calm and peaceful, then rough and boisterous, and then dangerous and treacherous. Have you not noticed how that at one election the people will whimsically submerge some political party or some candidate in a great deluge of disgust and in the very next election raise them to the superlative crest of popular favor. To attempt to pacify the people is as difficult as it would be to pacify the waters of the sea. Man could accomplish no more than the legendary Canute who tried to sweep back the waves. Nothing seems more futile, so restless as this human sea!"
