Christians believe in Jesus for the same reason some people worship cow's asshole: because they haven't thought things through, and they haven't thought things through because they are forbidden from thinking rationally about Jesus. They are allowed to think about him, but only in the form of a praise.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
