Was just reading both these books Hell on Trial The Holiness of God and they will drive you to your knees and in prayer as I just was for the state of the lost. The Hell book looks at every major passage in the entire Bible and examines them in detail and proves the case for eternal punishment and condemns universalism and annihilationism. The author writes with such clarity of detail and compassion as anyone whom reads it seriously will be moved. If you know unbelievers or want to send out random letters to the lost, and anytime you get in a conversation the doctrine should come up. Sadly Hell is not taken seriously by most these days and most evangelism and also gospel tracts either avoid it, or hardly emphasize it. Sad... Do you understand the most important attribute of God? Do you love God and want to know why he must punish sinners? The Holiness of God is a book that will examine in detail major passages in the Bible on God's holiness and divine justice that are very often ignored in modern day pulpits and books.
