I'm dedicating this page to this statement by PKM. . . . and maybe responding as well to Spazz for calling me a chicken**** cya guy on my doctrinal flight in "Brighamite" godhead concepts.
God indeed knows the truth. Solid self-awareness, objective self appraisals ongoing, and in fact being so compactly coherent in every aspect of His person, He probably hasn't woken up once in the last six thousand years with any doubts about Himself at all.
A lot of critics of Mormonism have never understood why a Mormon can believe in God the way Brigham Young did. Brigham Young was a Methodist of some learning, and made the observation from his experience that he never met anyone who could answer his questions about God until Joseph Smith did.
Sydney Rigdon was a proto-Baptist minister with strong Trinitarian notions, who gave way as well when Joseph Smith published his account of meeting the Jehovah of the Old Testament and His Son Jesus, the promised Messiah and our Saviour.
There are many instances of where Sydney Rigdon and many others changed their views. . . . every person associated with the early testimonies concerning the Book of Mormon, and every person close enough to Joseph Smith to be aware of his comings and goings. ... everyone gave way when the Prophet Joseph explained it to them, who had anything to do with the early Mormon history.
General Authorities of the LDS Church will dodge the question and profess actual ignorance of who God is, unless they somehow have a faint grasp of the notion that we have a Heavenly Father and a Saviour. They might not think the details of the scripture are as accurate as their own notions, or they may just want to be easily understandable to the general public. Not many of the current staff have related personal experience as Joseph Smith did.
But Joseph Smith was right. Joseph Smith knew who God is, and who our Saviour is.
