Some Christians claim to be able to heal the sick and even raise the dead. Some people applaud this, while others are skeptical. Are these healers using the power of God? Are they faking? Or is their power from Satan? And what about nonbelievers who also claim to perform wonders? Are they tricksters or agents of the occult? Can we believe their claims about past lives, seeing the future, UFO encounters, and spirit channeling?

Norman L. Geisler takes a sane and solidly biblical look at miraculous healings and other amazing phenomena today. With penetrating insight, he constructs guidelines for judging whether any so-called miracle is truly from God or from the realm of the demonic. Signs and Wonders also includes material on speaking in tongues and on the use of objects in faith healing. In addition, Geisler looks carefully at the clever trickery that charlatans use to dupe and swindle people. He shows that what often passes as supernatural can be explained as merely unusual.

Here is a book for anyone who wonders about the power and the sincerity of those who claim to be wonder-workers.
