As we move closer to the Rapture and Tribulation, Satan and his demons will become more and more deceptive through their power. The Bible extensively documents Satan and the demons' power, such as fire from the sky, control over nature, visions, possession, and enchantments.

Deceiving by Signs is an in-depth study of Satan and the demons' character and powers. It also addresses modern expressions of their abilities and offers and explanations for otherworldly experiences like aliens, Bigfoot, magic, psychics, and more. Speculation is also given for how Satan might deceive the world into not believing in Jesus throughout the signs of the Tribulation. Through learning more about God's adversaries we can be better equipped to discern the signs we encounter.

The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.

II Thessalonians 2:9-10
