I read the following from “A letter to God”, where Shuya Wang cited John Parker in Chinese. I translated into English, if I find the English version, I would like to read it and compare.
if you don’t believe the cancer is arranged by God, you will waste your cancer. If you think cancer is a curse rather than a gift, you will waste it. If you seek compassion from the probability of cure, rather than from God’s promise, you will waste your cancer. If you refuse to think over your cancer, you will waste it. If you let your cancer being the excuse to be isolated from people, rather than trying your best to strengthen your relationship with others, you will waste it. If you are desperate like those who lost hope, you will waste your cancer. If you treat your sin randomly as you were, you waste your cancer.
