I grew up in a tradition where true discipleship was focused on right teaching, right belief, and right practice of the Christian tradition. When we read the words of Jesus in the Sermon on the Mount, true discipleship is more focused on how your life is transformed through relationship with Jesus where his teachings are put into practice and lived out in community as salt and light for the world. Receiving Jesus's words and having a right understanding of them does not matter if they are not lived out in your day to day life.
