As God is, man shall become; As God was, man is.
This is the essence of Mormonism.
God was once a man and he became a god.
In the future we all shall become gods.
Some other beliefs:
God had sexual relations with Mary to make the body of Jesus, (Brigham Young, Journal of Discourses, vol. 4, 1857, p. 218; vol. 8, p. 115).
"Therefore we know that both the Father and the Son are in form and stature perfect men; each of them possesses a tangible body . . . of flesh and bones," (Articles of Faith, by James Talmage, p. 38).
After you become a good Mormon, you have the potential of becoming a god, (Teachings of the Prophet Joseph Smith, p. 345-347, 354.)
The first spirit to be born in heaven was Jesus, (Mormon Doctrine, p. 129).
Jesus and Satan are spirit brothers and we were all born as siblings in heaven to them both, (Mormon Doctrine, p. 163; Gospel Through the Ages, p. 15).
Jesus' sacrifice was not able to cleanse us from all our sins, (murder and repeated adultery are exceptions), (Journal of Discourses, vol. 3, 1856, p. 247).
If it had not been for Joseph Smith and the restoration, there would be no salvation. There is no salvation [the context is the full gospel including exaltation to Godhood] outside the church of Jesus Christ of Latter-day Saints, (Mormon Doctrine, p. 670).
