Why did God forbid John from writing down what the seven thunder's said? What purpose does this serve?
In other words, the thunders described the Great Disappointment of 1844 beforehand to John. Why would something like that need to be given to John is of course another question, one we may not be able to answer. This explanation is in the context of concerns of people who went through the Great Disappointment and was perhaps not intended to be taken as an absolute. While it may seem a bit parochial, there is no reason why that explanation is not the valid one, nor is there any reason why the messages given to John did not include other secrets besides the Great Disappointment of 1844, secrets of which we know nothing.
