This is the way our Heavenly Father became God. Joseph Smith taught: It is the first principle of the Gospel to know for a certainty the character of God. . . . He was once a man like us; . . . God himself, the Father of us all, dwelt on an earth, the same as Jesus Christ himself did (Teachings of the Prophet Joseph Smith, pp. 345-46). (Gospel Principles, 1997. Chapter 47 EXALTATION).
We believe in a God who is Himself progressive, whose majesty is intelligence; whose perfection consists in eternal advancement -- a Being who has attained His exalted state by a path which now His children are permitted to follow, whose glory it is their heritage to share. In spite of the opposition of the sects, in the face of direct charges of blasphemy, the Church proclaims the eternal truth: 'As man is, God once was; as God is, man may be.'" (LDS Apostle James E. Talmage, Articles of Faith, Ch.24, p.430 - p.431, LDS Collectors Library '97 CD-ROM)
" 'It is the first principle of the gospel to know for a certainty the character of God,' the inspired word continues, 'and to know that we may converse with Him as one man converses with another, and that He was once a man like us; yea, that God himself, the Father of us all, dwelt on an earth, the same as Jesus Christ Himself did.' The Father is a glorified, perfected, resurrected, exalted man who worked out his salvation by obedience to the same laws he has given to us so that we may do the same." (LDS Apostle Bruce R. McConkie, A New Witness for the Articles of Faith, p.64, LDS Collectors Library '97 CD-ROM)
Thus, on this beautiful spring morning in the Sacred Grove, Joseph Smith witnessed the renewal of God's dealing with his children in accordance with the great gospel plan of redemption. Upon this occasion God the Father and his Beloved Son Jesus Christ appearing as glorified Resurrected Beings unto a chosen servant of God, made known once again the state of immortality which man will attain in preparation for the next estate of eternity; that also the world once again could know the reality of the personal nature of God the Father and his Beloved Son.

"God: Creator And Ruler Of Many Worlds. -- While it is true that evolutionists may be divided between theistic and atheistic groups, yet most of those professing belief in God consider him to be an indefinable force, essence, or power of an incomprehensible nature. According to revelation, however, he is a personal Being, a holy and exalted Man, a glorified, resurrected Personage having a tangible body of flesh and bones, an anthropomorphic Entity, the personal Father of the spirits of all men. (D. & C. 130:22- 23; Moses 6:51, 57; Abra. 3:22-24; Jos. Smith 2:16-19.)"
"We are members of the family of the Eternal Father. He is a glorified and exalted and eternal Being, having a resurrected body of flesh and bones. His name is God, and the kind of life he lives is God's life. His name is also Eternal, and the name of the kind of life he lives is eternal life. Eternal life is God's life, and God's life is eternal life. We are commanded to be perfect as he is perfect and to advance and progress until we become like him, or in other words, until we gain eternal life. Thus Joseph Smith said, "You have got to learn how to be Gods yourselves, and to be kings and priests to God, the same as all Gods have done before you, namely, by going from one small degree to another, and from a small capacity to a great one; from grace to grace from exaltation to exaltation, until you attain to the resurrection of the dead, and are able to dwell in everlasting burnings and to sit in glory, as do those who sit enthroned in everlasting power." (Teachings, pp. 346-47.) Christ our Lord has so obtained, thus enabling him to say to the faithful: "Ye shall be even as I am, and I am even as the Father." (3 Ne. 28:10.)" (LDS Apostle Bruce R. McConkie, The Mortal Messiah, Vol.1, p.23 - p.24, LDS Collectors Library '97 CD-ROM)
"This was the calling of Joseph Smith. He taught anew that God was in the form of man; that man was made in the image of God; and he taught the principles of justice, mercy, charity, and forgiveness. ... He taught the truths that the Prophets before him had taught; and he went beyond them. ... Joseph Smith taught men to look up to heaven and conceive of a God in the form of man. He taught them that they could become like their Father and God, who was 'an exalted Man.' And what is more simple and reasonable? Don't you parents expect your children to become like you? Or do you expect your children to be something else than men and women? No. You men will see your sons become men; you women will see your daughters become women. Then God our Father--yes, and our Mother--in heaven, looking down upon this world-- this school house in which their children are being educated--expect, and Joseph Smith taught it as a truth, that their children will be exalted, if they pursue the proper course, until they shall become divine beings themselves, worthy to stand upon that plane where stand their Father and their Mother in heaven. Like begets like; and the principle of eternal progress will make of man a God. (LDS Apostle Orson F. Whitney, Collected Discourses, Vol.5, May 8, 1898, LDS Collectors Library '97 CD-ROM)
So much for this never being LDS docterine!
