I finally finished reading Kevin Swanson's "Apostate, The Men Who Destroyed The Christian West". (The book is here on Amazon and Kevin's web site is here.) He lays out a convincing and powerful argument that ideas have consequences.
Most illuminating is the historical background he provides for each of the figures he identifies as a key apostate - i.e., demonic possession, insanity, suicide, mass-murder, adultery, homosexuality, cultural and social revolutions, and unbridled, maniacal apostasy. Satan excels at marketing evil as good (2 Cor 11:14). While new Christians may have difficulty discerning apostasy, a good place to start is the examination of one's life. A bad tree will bear bad fruit. Jesus warned us that we would know apostates ultimately by their fruit.
Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits. (Matt 7:15-20, ESV)
Unfortunately, it is increasingly common to ignore the fruit of one's life, especially if they happen to be unusually gifted or talented. History is littered with the ruin of great thinkers whose personal lives smacked of rotted fruit, and yet whose ideas and worldviews were (are) warmly embraced as prophetic genius.
In contrast, Kevin's life is bearing good fruit, earning him at least a hearing in the church. We ignore him at our own peril.
