(This first part was so well written, I am quoting directly from the site.)
Many of us live our lives no differently than do conservative non-Christians, except for the fact that we attend church regularly each week. We watch the same entertainment. We share the same concerns about the problems of this world. And we are frequently just as involved in the world's commercial and materialistic pursuits. Often, our being "not of this world" exists in theory more than in practice.
But the church was not originally like that. The first Christians lived under a completely different set of principles and values than the rest of mankind. They rejected the world's entertainment, honors, and riches. They were already citizens of another kingdom, and they listened to the voice of a different Master.

(History of the
Letter to Diognetus @ 130 AD
-Yet, although they live in Greek and barbarian cities alike, as each man's lot has been cast, and follow the customs of the country in clothing and food and other matters of daily living, at the same time they give proof of the remarkable and admittedly extraordinary constitution of their own commonwealth.
-They live in their own countries, but only as aliens. They have a share in everything as citizens, and endure everything as foreigners. Every foreign land is their fatherland, and yet for them every fatherland is a foreign land. They marry, like everyone else, and they beget children, but they do not cast out their offspring. They share their board with each other, but not their marriage bed.
-It is true that they are "in the flesh," but they do not live "according to the flesh. They busy themselves on earth, but their citizenship is in heaven. They obey the established laws, but in their own lives they go far beyond what the laws require. They love all men, and by all men are persecuted. They are unknown, and still they are condemned; they are put to death, and yet they are brought to life. They are poor, and yet they make many rich; they are completely destitute, and yet they enjoy complete abundance. They are dishonored, and in their very dishonor are glorified; they are defamed, and are vindicated. They are reviled, and yet they bless; when they are affronted, they still pay due respect. When they do good, they are punished as evildoers; undergoing punishment, they rejoice because they are brought to life. They are treated by the Jews as foreigners and enemies, and are hunted down by the Greeks; and all the time those who hate them find it impossible to justify their enmity.
-To put it simply: What the soul is in the body, that Christians are in the world. The soul is dispersed through all the members of the body, and Christians are scattered through all the cities of the world. The soul dwells in the body, but does not belong to the body, and Christians dwell in the world, but do not belong to the world.
Recap:
True Christians proved (by their behaviour) the remarkable and extraordinary foundation of Christ.
They shared everything. They endured everything.
They did not cast out their children.
They shared housing, but did not commit adultery.
They did not live worldly (for self pleasure).
They went beyond what the law required.
They loved all men, even if persecuted by them.
They were poor, destitute yet enjoyed abundance and made others rich.
They blessed when reviled and paid respect even when insulted.
Can the world say these things about Christians today?
If not, why not?
