I also found it highly improbable that (a) attaining the "truth" would depend upon solving a cryptic puzzle hidden in the Bible; (b) such "truth" would be unavailable to the vast vast majority of humanity; and (c) not only was I born into Christianity, whose God is real, but I was born into a tiny sect with its own special prophet, who alone, unlike the rest of Christianity and the rest of humanity, possesses the secret "truth".
EGW's "prophecies" about the papacy, the sunday law and things like that can only be understood in the context of the virulent anti-Catholic views and attitudes rampant in Anglo-saxon protestant circles of the USA in the early-mid 19th century. Coupled with the religious effervescence in New England and upstate New York at the time, one can begin to understand how the "standard" SDA eschatology arose. But to ascribe any prophetic truth to Uriah Smith's, EGW's and their fellow travellers' fanciful musings about a "Sunday law" is taking it a little too far.
