If a man loves God and is called according to His purpose, then that man can know for a certainty that all things will work together for good.
A man who truly believes he loves God and is called by God should have a rock solid assurance in all he does. Fear of all things temporal should be eliminated. Confidence will override the system.
If this were true, this man’s life would be marked by risk-taking, abundant giving, and boundary pushing efforts.
The immediate response to this logic is that it’s testing God or arrogant, short-sighted and dangerous. If a normal guy does this, I would agree. But a man who loves God and is called according to His purpose?
I don’t think these concerns are the issue!
If you know for sure that you love God and you are called according to His purposes you will undertake a life of radical faith, obedience, service, ministry, and giving. A life that few live, for few have confidence in the One who calls.
Don’t apply this verse only to people who get cancer. Apply this verse in all areas of life. It’s high time to wake up, live in the day, in the Light of Him who has called you. This will result in a particular way of life not many have seen, let alone lived.
“But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light”
anti-itch meditation 
I thought you were not going to mention that book you were reading? (heh)
Oh no, this is not from that book! That book didn’t even get close to scaling such lofty heights. Not even close to inspiring such lofty thoughts. Don’t get me started!
Well, do we really love God? That is where the rubber meets the road my brother. I think our faith is tied to how much we treasure Christ. And if that’s the case, I’m a lousy lover to be honest.
“A life of radical faith…” Amen! Don’t let your left hand know what you’re right hand does.
We only need to be aware of the danger of fanaticism, which is when we are radical, but not according to the Word.
That reminds me of something I just read. It’s from a website on George Mueller…here’s the first part (pardon the length):
Reasons Which Led Mr. Mueller To Establish An Orphan House
“I HAD constantly cases brought before me which proved that one of the especial things which the children of God needed in our day was to have their faith strengthened. For instance: I might visit a brother who worked fourteen or even sixteen hours a day at his trade, the necessary result of which was that not only his body suffered, but his soul was lean, and he had no enjoyment in the things of God. Under such circumstances I might point out to him that he ought to work less, in order that his bodily health might not suffer, and that he might gather strength for his inner man by reading the word of God, or by meditation over it, and by prayer. The reply, however, I generally found to be something like this:
“‘But if I work less, I do not earn enough for the support of my family. Even now, whilst I work so much, I have scarcely enough. The wages are so low, that I must work hard in order to obtain what I need.’
“There was no trust in God. No real belief in the truth of that word:
“Seek ye first the kingdom of God, and His righteousness: and all these things shall be added unto you.”
“I might reply something like this:
“My dear brother, it is not your work which supports your family, but the Lord; and He who has fed you and your family when you could not work at all, on account of illness, would surely provide for you and yours if, for the sake of obtaining food for your inner man, you were to work only for so many hours a day as would allow you proper time for retirement. And is it not the case now, that you begin the work of the day after having had only a few hurried moments for prayer and when you leave off your work in the evening, and mean then to read a little of the word of God, are you not too much worn out in body and mind to enjoy it, and do you not often fall asleep whilst reading the Scriptures or whilst on your knees in prayer?”
“The brother would allow it was so; he would allow that my advice was good but still I read in his countenance, even if he should not have actually said so,
“‘How should I get on if I were to carry out your advice?’
“I longed, therefore, to have something to point the brother to, as a visible proof that our God and Father is the same faithful God as ever He was; as willing as ever to PROVE Himself to be the LIVING GOD, in our day as formerly, to all who put their trust in Him.– ”
