"To their contemporaries, the first Christians were a most peculiar breed. They didn’t participate in the diversions and activities that everyone else did to satisfy certain lusts of the flesh (1 Pet. 4:1-4). They publicly and at no small cost repudiated cultural activities or artifacts that represented a worldview contrary to the teaching of Christ (Acts 19:18-20). They didn’t keep their religion to themselves, either; in fact, Jesus Christ was so much a part of their daily conversation that their unbelieving neighbors took to calling them the 'Christ-ones' (Acts 11:26)."
