Christianity is simple; it's meant to be accessible to everyone, regardless of era or culture. Joining the
club is easy; being a
member is hard - it's a
life's
work, and no one ever gets it
perfect. If someone has "done a bad deed", it's not the
religion's fault: it's the person's fault (see
religion and violence). A true
Christian is someone who has accepted the
salvation offered by
Christ via his death as the
sacrificial lamb for our
sins; messing up != returning the Gift, though one's Christian life, or lack thereof, may consist of returning it (the old "faith + good works = salvation" equation).
