As a result of his belief in an intelligent evil having a destructive influence on God's good creation, and in honor of his first wife who died of cancer in 2001, Ralph Winter founded the Roberta Winter Institute to advance the cause of disease eradication. Winter devoted much of the final decade of his life to the RWI, seeing disease eradication and our response to evil in general as overlooked frontiers in mission. The institute seeks to mobilize believers to fight the origins of disease, thereby defeating the works of Satan and glorifying God.
