Most people, regardless of their understanding of him, admire Jesus, and see him as a genuinely great person. Perhaps it’s because Jesus fits well with the Australian culture, which values such things as helping a mate, putting yourself out so that others can have a better life, or even going out on a limb against the establishment because of injustice.
These were the attributes of Jesus’ life, this is what he did, this was his mission, and we believe that he wants them to be ours as well.
