Lutherans believed that reading the Bible was the only way to learn a good life

I'm not sure if this is a true/false question, but if so, I would say TRUE but also add much more context to the answer.

Martin Luther led the Reformation in Germany in the 16th century that broke away from the Roman Catholic Church. Luther's followers became known as "Lutherans," though they referred to themselves as "Evangelicals" (gospel believers). Luther translated the Bible into German because yes, he believed that the Bible was the only real source of spiritual truth. "Sola Scriptura" - - Latin for "Scripture alone" - - was one of his mottoes. Luther and the Lutheran church rejected church hierarchy and tradition as sources of truth in themselves, and believed all truth had to come from study of the Bible.

The core idea of Lutheranism was that "evangelical" idea - - that the way to a "good life," or maybe better expressed, the way to eternal life and salvation with God, was through the gospel (the good news) that Jesus had sacrificed himself to atone for the sins of the world. Believing in Jesus was the path to eternal life, which was not something humans could earn by their own works or efforts.
