Because they:
OBEY ALL LAWS, even inconvenient ones, like speed limits when late for work;
PAYING TAXES, rather than claiming religious exemption;
KEEPING THEIR WORD, like to the IRS on not promoting politics in church;
TEACH YOUTHs to wait until marriage instead of having sex for fun and just using protection;
TREAT YOUTHs with respect, and not just a "do what you're told!" attitude;
TEACH YOUTHS the whole Bible, and not just Bible stories, right along side parents;
DON'T LET INDIVIDUALS get lost in the crowd of an oversize church;
TEACH EVERYONE the same, making it easier to start a new congregation, with a set of elders;
MAKE sure every member is evacuated in a natural disaster, such as in Katrina, and not just the good contributors;
BUILD CHURCHES that compliment neighborhoods, lacking large and expensive decorative features;
