 Eric Metaxas is the New York Times bestselling author of the book Bonhoeffer and host of the nationally syndicated Eric Metaxas radio show. Israel understands that in order to have shalom, in order to have peace, sometimes you have to fight and you have to be willing to fight. Why? Because there is evil in this world. If you don't understand that there is evil in this world, evil will triumph. Israel understands that we have a right to exist.
