I don't care where you are in the world, science and governments have not been able to read your thoughts, let alone determine your beliefs, unless you express them. Put on an armband, (figure of speech)and I guarantee that someone will notice it and either comment on it or form some opinion about you. Privacy is your most fundamental right, and you exercise it between your ears! It is clearly no one's business what you think or believe. In a small, densely populated area like Japan, privacy is practically non-existent, yet people quietly enjoy their personal thoughts. Something so simple should be universally understood, but it is missing in so many lives. Pity.
I'm not sure if you were responding to my post. But if you were, here's my response.
Christianity doesn't work that way--limited to the quiet recesses of your mind. One of Christ's last directives to his disciples was to tell all people about Him. It's called the Great Commission and that's why we're kind of a noisy bunch. It's why every one of Christ's apostles died a martyr's death. They wouldn't shut up.
That's what's happening in China now to the enormous consternation of the authorities. In the past 15 years, the best estimates are that between 50 and 100 million Chinese have become Christians--mostly Roman and Evangelical and the rate of conversion is increasing. So it's not the 'safe' denominations that have watered down the Gospel to the point of meaninglessness. It's the dangerous ones that ask their members to change how they think and behave profoundly and to spread the word.
The Chinese churches are now confidently stating that they no longer need Western missionaries--they are self-sustaining. Instead, they have started sending missionaries to Europe where they correctly perceive the Gospel is more sorely needed than in their country.
This represents an enormous cultural change, even in a country the size of China. The Confucian and Christian worldviews could not be more different. I regard this mostly unremarked growth as every bit as important a change in China as the surging economy and the surfeit of boys due to China's mandatory abortion policy.
The Chinese authorities will be no more successful at squashing this historic change than were the Romans able to silence early Christians by murdering one after another. For some reason, historically, the Gospel spreads most rapidly under persecution.
