The reason I don't get the flu is because I pray to God.

The psychiatric ward is awaiting you, DUMBecker.
You can't keep yourself alive. You will die.
God doesn't want you to die. But since you can't keep yourself alive, what could God do?
God sent His son, Jesus, in the form of a man, a man that has the strength of God, to handle all the complexity of nature that mankind and its science can't.
Jesus perfected the way to eternal life for all of us. And He offers it freely, because there is no way that we could ever pay enough to buy it from Him.
The only thing that Jesus requires is faith that He will do it for us. But that faith has to be on an individual basis, since there are those who will never believe.
I will live forever, because I accept Jesus salvation. If Jesus doesn't return before I die, then I will be resurrected with all dead people at the last day. After that, I will receive everlasting life.
Incidentally, when Jesus perfected eternal life for us all, He did an upgrade on us. Our new life will be a super-powered life when compared with this life. It will be one wherein we will never be able to die. Because of this, make sure that you are believing in Jesus salvation. Because if you reject, you will still receive the everlasting life, even though you are cast out by God.
There is nothing you can do about it... one way or another. Why not? Because God is in control. Either you accept God, or you will be cast out into an everlasting, living destruction, at the time of the resurrection.
