What would convince me that Jesus is real? People pray for peace, and then all wars in the world stop permanently. That good things happen exclusively to good people and bad things happen exclusively to bad people. That we see Christians moving mountains around with their faith, and they stop a hurricane with their faith. That a woman doesn't die in childbirth every two minutes as is the case now.
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"
