Are there always good reasons to get out of bed in the morning? This book argues that there are, citing the line of poetry from Virgil’s Aeneid that is inscribed at the World Trade Center memorial: ‘No day shall erase you from the memory of time’. It traces fascinating parallels between the role played in the Aeneid by deceitful gods and the role played in the Bible by a deceitful Devil, and explains how Jesus, respecting our free will, offers us eternal happiness, but refuses to convert us by force.
