In Latter-day Saint teachings, hell is more of a temporary state than a permanent destination for most souls. This belief reflects the restoration of a loving, just, and merciful God, emphasizing opportunities for redemption and growth beyond this life.

Latter-day Saints believe that after death, those who have not repented of their sins may go to "spirit prison," a state sometimes equated with hell (see Doctrine & Covenants 138:32). Here, individuals suffer for their own sins if they haven't accepted the Atonement.

This version of hell is temporary for the vast majority of souls. The emphasis is on learning, repentance, and eventual resurrection through Christ’s Atonement (see 1 Peter 3:19-20, and Doctrine & Covenants 138).

Permanent hell, often referred to as "outer darkness" in Latter-day Saint terminology, is reserved for very few, namely the sons of perdition. These are individuals who have had a full knowledge of Jesus Christ's divinity, experienced His power, and then fully rejected Him (see Doctrine & Covenants 76:32-37).

The Latter-day Saint conception of hell holds similarities but also important and unique differences from the mainstream Christian understanding of it. 

Similarities

• Emphasis on Justice and Mercy: Like many Christian faiths, Latter-day Saints emphasize God’s justice for unrepentant sin and His mercy through Jesus Christ.
• Existence of Hell: Similar to Catholic and Protestant beliefs, hell exists as a part of the afterlife for those who reject God.

Differences

• Temporary vs. Eternal Hell: Many traditional Christian denominations portray hell as eternal for all who reject God, whereas Latter-day Saints believe only a small fraction, namely the sons of perdition, will face eternal damnation.
• Opportunities for Redemption: Latter-day Saint theology uniquely allows for repentance and acceptance of the gospel even after death, contrasting with the more fixed post-mortem judgment seen in many Christian faiths.
• Inclusion of Spirit Prison and Paradise: The Latter-day Saint belief in spirit prison where spirits can learn and accept the gospel is distinct, with no direct equivalent in many other Christian doctrines.

Modern-day prophets and apostles have often focused on the hopeful and redemptive aspects of the gospel plan. Leaders like President Dieter F. Uchtdorf have emphasized that Christ’s Atonement provides a way for all to be redeemed from sin and mistakes, highlighting an inclusive opportunity for eternal joy.

Latter-day Saint theology views hell as smaller and more temporary for most than depicted in many traditional Christian doctrines. This perspective aligns with broader teachings about a loving and merciful Heavenly Father eager to provide all His children with every opportunity to return to Him. The focus is on growth, progression, and redemption, with a small permanent hell reserved only for those who utterly reject God after knowing His truth.
