Book excerpt: A curse is the opposite of a blessing. They are quite real. When Jesus cursed the fig tree, it was not without a very dramatic effect. The result evoked astonishment - as it indeed would if a curse runs through your family. But let me quickly state that in the realms of the spirit certain things are far beyond the possibility of what demons can do. It is God who judges people and decides on their eternal fate. Demons cannot just go on rampage kidnapping and destroying people's lives without a cause. For a curse therefore to have effect on any person or any group of people, there must be a cause, which renders the offender and possibly his descendants vulnerable to imprecation of divine punishment.
