An Unchangeable God

There is a God in heaven, who is infinite and eternal, from everlasting to everlasting the same unchangeable God, the framer of heaven and earth and all things which are in them. DOCTRINE & COVENANTS 20:17

Joseph Smith taught that God “changes not, neither is there variableness with him; but that he is the same from everlasting to everlasting, being the same yesterday, today, and for ever; and that his course is one eternal round, without variation” (Lectures on Faith, 3:15). God’s plan for the creation and redemption of his children is eternal; his work and glory — “to bring to pass the immortality and eternal life of man” (Moses 1:39) — is forever the same. Nephi taught that God is unchanging, “and the way is prepared for all men from the foundation of the world, if it so be that they repent and come unto him” (1 Nephi 10:18). Policies and procedures in the administration of the Lord’s Church may change, but the principles are eternal, for “God doth not walk in crooked paths,... neither doth he vary from that which he hath said, therefore his paths are straight, and his course is one eternal round” (D&C 3:2).
