"The Beast from the Sea" is the collective unconscious animal instinct of people, which motivates them to strive for wealth and prosperity, to create a world civilization that provides a comfortable life, access to all benefits INDEPENDENTLY of God.
This "beast" tempted the Jews to follow the interests of the flesh in defiance of the desire for the Kingdom of God that Abraham followed. The seven "heads" of the beast are 7 empires: Ancient Egypt, Assyria, Babylon, Medo-Persia, Greece, Rome and the USA.
"The mark of the beast" is the habit of lying (mark on the forehead) and the habit of stealing (mark on the right hand), this way of acting helps to achieve success in today's world.
The name of the beast is Wealth or Prosperity (see Acts 19:25):
εὑπορία = (5 + 400 + 80 + 70 + 100 + 10 + 1) = 666
The world favors those who live in the name of Wealth.
"The number of the name of the beast" is any form of state registration of a person or organization in this world: ID, passport, cadastral number, tax number, etc. Having the "number of the name of the beast" allows a person to enjoy the benefits of civilization. This number, 666, is the opposite of the number 144,000, which is registration with God, in the Church - in one of the 144,000 communities throughout the history of the Church, led by the Holy Spirit (they had the seal of the Holy Spirit). 144,000 cannot be registered in this world, they do not have signs of state registration - they are not denominations of religion, or registered communities, they are purely informal associations around the saints.
"Count the number of the beast" is God's command that we find the essence of this evil and reject the universal human pursuit of wealth. Literally, this name of the beast is counted as the numerical value of one word found in the Greek text of Acts 19:25.
