"He who through faith is righteous shall live."
From this line in the Bible, "He who through faith is righteous shall live", Luther concluded that no amount of good works will promise you salvation. He inferred that all anyone had to do was have faith and they would be saved. An example of good works were buying *indulgences. He believed that the Church was corrupt and had lost sight of what was right.
*Indulgences: were certificates issued by the pope that were said to reduce or even cancel punishment for a persons sins.
