and that nobody might be able to buy or sell except a person having the mark, the name of the wild beast or the number of its name.

Revelation 13:16-

In imitation, Satan uses the demonic mark of the wild beast. Anybody engaged in everyday activities such as buying and selling is pressured to do things the way the wild beast does, as, for example, in celebrating holidays. They are expected to worship the wild beast, letting it rule their lives, so as to receive its mark.

36. Those who refuse to accept the mark of the wild beast have had what problems?

³⁶ Those who refuse to accept the mark of the wild beast have had constant problems. Starting in the 1930’s, for example, they had to fight many court battles and endure violent mobbings and other persecutions. In the totalitarian countries, they were thrown into concentration camps, where many died. Since the second world war, countless young men have suffered lengthy imprisonments, some even being tortured and killed, because of their refusal to compromise their Christian neutrality. In other lands Christians are literally unable to buy or sell; some are unable to own property; others are raped, murdered, or chased from their native land. Why? Because in good conscience they refuse to buy a political party card.d​—John 17:16.

37, 38. (a) Why is the world a difficult place for those who refuse to have the mark of the wild beast? (b) Who are keeping integrity, and what are they determined to do?

³⁷ In some areas of the earth, religion is so ingrained in community life that anyone who stands for Bible truth is ostracized by family and former friends. It takes great faith to endure. (Matthew 10:36-38; 17:22) In a world where the majority worship material wealth and where dishonesty is rampant, the true Christian often has to trust implicitly in Jehovah that He will uphold him in pursuing an upright course. (Psalm 11:7; Hebrews 13:18) In a world awash with immorality, it takes great determination to remain clean and pure. Christians who fall sick are often pressured by doctors and nurses to break God’s law on the sanctity of blood; they even have to resist court orders that conflict with their faith. (Acts 15:28, 29; 1 Peter 4:3, 4) And in these days of rising unemployment, it is becoming increasingly difficult for a true Christian to avoid work that would mean compromising his integrity before God.​—Micah 4:3, 5.

³⁸ Yes, the world is a difficult place for those who do not have the mark of the wild beast. It is an outstanding demonstration of Jehovah’s power and blessing that the remaining ones of the seed of the woman, as well as more than six million of the great crowd, are keeping integrity despite all the pressures to break God’s laws. (Revelation 7:9)
