Ironically that nasty Satan is a believer though perhaps having actually had the confidence that he could succeed when he led the rebellion against his Creator (Elohim), but now he knows (believes) his time is short because he sees the many ancient prophecies already fulfilled (such as Jesus Christ’s death then resurrection) and many more soon to manifest, so his desperation will only increase while the light of the Messiah will shine brighter and brighter as His return approaches, millions becoming born again.
