“Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore whoever resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of the one who is in authority? Then do what is good, and you will receive his approval, for he is God's servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God's wrath on the wrongdoer. Therefore one must be in subjection, not only to avoid God's wrath but also for the sake of conscience. ...”
Ah, so the answer was right there in scripture all along. The Chinese Christians and Muslims who are being persecuted must be doing wrong, or else they would be receiving the approval of the God-appointed authorities who govern them, who are God's servants for their good.
So, what is your complaint? Do you want Western atheists to fight God for you, in order to rescue people who have clearly incurred God's wrath? Shouldn't you instead be telling those persecuted Chinese Christians and Muslims to do what is good and be in subjection, so that they can receive the approval of the government that God has instituted there?
