Faith is the response of the total self, the mind, will and affections.  Being justified is a personal phenomenon.  Service and love are more important than right beliefs and sound doctrine.  You do your own believing.  God transforms the heart and you experience God’s love.  Good works are a correlation to faith.  Protestants love the apostle Paul.  They have a tendency to over emphasis the written Bible with an emphasis on private religious experience.  Diversity is good, since most Protestant groups have broken off from another Protestant group or from the Roman Catholic Church.  In a certain sense heretical or diverse views are expected rather than one orthodox single view.
