How do we know that hell is a real place of punishment?

The existence of hell as a place of punishment is substantiated by both the Old and New Testaments. Jesus speaks directly about hell, using imagery of unquenchable fire and eternal suffering, expressing its seriousness. In Isaiah 66:24, the text reflects that the suffering is everlasting and public, making it a significant warning. Revelation 20:10 describes the devil being thrown into the lake of fire, which further affirms the eternal judgment awaiting those who reject God's truth. Thus, hell is presented not as a mere metaphor but as a literal reality for those who transgress against God.
