All hinges on God's ordinations. Having this understanding is true faith in God. If God allows you to live, you won't die no matter how sick you get. If God does not allow you to live, then even if you are not sick, you will still die if that is what must be. The span of your life is predetermined by God. To know this is true knowledge and true faith. That God makes people fall sick is not random; it's a way to refine their faith. It's suffering that people must endure. If He makes you fall sick, do not try to escape it; if He does not, then do not request it. All is in the Creator's hands, and people must learn to let nature take its course.

Nothing in nature is random; it all comes from God. This is true. Among sufferers of the same disease, some die and others live; all of this was predetermined by God. If you can live, it proves that you have not yet completed the mission God gave you. You should work hard at completing it, and cherish this time; do not waste it. If you are sick, don't try to escape it, and, if you are not sick, do not request it. In any matter, you cannot get what you want merely by requesting it, nor can you escape anything just because you want to. No one can change that which God has decided to do.
