Jesus proclaimed, Repent, for the kingdom of heaven is at hand. .. He is saying that a whole new order is about to enter history, and if you want to be a part of it, you will need a change so fundamental that the Gospel of John would later refer to it as a "new birth". Being born again was not meant to be a private religious experience that is hard to communicate. .. but rather the prerequisite for joining a new and very public movement - the Jesus and kingdom of God movement.
