Here are quotes from LDS prophets and scriptures that reflect this doctrine:
“As man now is, God once was: As God now is, man may be.”
— King Follett Sermon, Joseph Smith, April 1844
(Often cited as one of the clearest statements of this doctrine.)
“The glory of God is intelligence, or, in other words, light and truth.”
— Doctrine and Covenants 93:36
(While not a direct quote from a prophet, this revelation from Joseph Smith underpins the path to becoming like God.)
“We believe that all men and women are capable of becoming like God.”
— Brigham Young, President of the Church (1850s)
“The highest and holiest aspiration of a Latter-day Saint is to become like God.”
— Elder Russell M. Nelson, The Teachings of Jesus Christ, 2012
