The warnings presented in the book of Jude resemble the countless spirit-filled churches that I personally have been acquainted with throughout my seventeen years in ministry. Unfortunately many of these same congregations have drifted into doctrinal compromise and spiritual lethargy because for of the age-old agents of destruction. Many of these assemblies where once strong towering beacons of end-time Holiness Pentecostal revival, but unfortunately they have succumbed to spiritual sleeper cells that have erupted in their congregations, causing spiritual damage that will last for generations. Jude's warnings to theses assemblies almost seems like a modern news article detailing the carnage that has been left in the wake of some horrible spy war that has leaked in the public sphere. To Them that are Sanctified, serves as a modern but Biblically commentary on who these anonymous infiltrators are, how to identify them, and how to overcome them.
