We have almost eliminated smallpox, and other plagues that disseminated the world in the past. Yet we still have diseases that shorten the lives of millions of people on this earth. With billions of dollars and years of research, we still have not conquered cancer, muscular dystrophy, Alzheimer’s disease, or HIV.
In the Tip of the Writing Brush is written:
Step by step, I am solely making preparations
truly to save the world. 4-36
After that, you may stay as long as you wish,
without illness, death, or weakening. 4-37
According to the Tip of the Writing Brush, God is preparing to save the world by helping mankind sweep the evils (greed, arrogance, and self love) from their minds. When this is accomplished, suffering including disease will be eliminated.
In conclusion, research and money spent to relieve the sufferings in the world is necessary and commended; but should we not also place as much or more resources to promote religion and God to eliminate evil from the minds of the world? We need to help people understand the root of the sufferings in this world (the law of cause and effect). When arrogance and greed is swept from all of our minds, science and medicine may eventually be allowed to eliminate all disease.
