diabetes and instant healing

I was surfing the channel recently and a morris cerulo program caught my eye-not because he was fundraising for his prayerline but because of a testimony from one of the callers. He said that he had faith that God had healed him of his diabetes. This is not because God can not heal today but i was hoping he had not just stopped cold turkey:stop taking their meds ,proper diet ,excersise and daily monitoring of thier sugars-but they had confirmed this healing not by fickle feeling but thru God's instruments of healing-his primary physician. If God did let us praise Him if He did not let us be like paul and bear our particular thorn of the flesh,rest securly in His sufficent grce and through our ouselves into His word,worship,prayer and fellowhip at our local church....
