Lutherans believe in the Triune God - Father, Son, and Holy Spirit - and that the Bible is the written Word of God, completely reliable and without error. They teach that humans are saved from their sins by God's grace alone, through faith alone, on the basis of Scripture alone. Lutherans also believe in the sacraments of baptism and communion, and that salvation is by grace through faith alone. They do not worship Martin Luther, but they do follow his teachings, which are based on the Bible. Lutherans believe that Jesus is the world's Savior from sin, death, and the power of the evil one, and that he won life for us by his perfect life, death, and resurrection from the dead
