Unknown His work and hospitality His work and hospitality In 1537, and again in 1541, Luther became so ill that his family and friends feared he would die. The Lord restored him to health, however, and enabled him to continue in his work. He lectured, preached, attended conferences, and wrote books and tracts. He and his wife Katie were well known for their hospitality. Even though they themselves often had little money, they welcomed anyone in need. Meals were usually times of lively conversation, as visitors talked with Luther about Scripture and its doctrines.
