The Danger of Unforgiveness and Spiritual Deception | Doctrines of Demons: RT Kendall

In this second episode unpacking his book Doctrines of Demons, RT Kendall delivers a deeply theological and pastoral message about the subtle dangers of false doctrine, the influence of Satan, and the critical importance of total forgiveness.

RT explains how doctrines of demons (1 Timothy 4:1) are not just theological errors but spiritual attacks that can infiltrate the church—even through well-meaning people. He dives into Calvinism and Arminianism, the danger of bitterness, and how the Holy Spirit’s anointing is the believer’s best defense against deception.

Drawing on Scripture and decades of experience, RT teaches that grieving the Holy Spirit through unforgiveness weakens a Christian’s ability to discern false teaching. Only by walking in total forgiveness can believers fully experience the ungrieved Spirit and the clarity that comes with His voice.

A historical-theological dive into the roots of Calvinism and Arminianism, and why RT doesn’t label either as demonic. He shares his personal journey from Wesleyan Arminianism to Reformed theology.

RT discusses how Satan, once trained in the “university of the heavens,” now uses his knowledge to plant deceptive teachings—even among sincere believers.

A major section: RT unpacks how bitterness, grudges, and unforgiveness give Satan a foothold in the life of a believer (2 Corinthians 2:10–11), dulling discernment and making it harder to hear the Holy Spirit.

RT shares how forgiving others transformed his life and deepened his ability to understand the Bible and discern heresy. He highlights total forgiveness as the gateway to experiencing the ungrieved Holy Spirit.

Quoting 1 John 2:20, RT teaches that the anointing—not education—is what allows believers to recognize spiritual error. He urges leaders not to lean on AI or intellect, but on the voice of the Spirit.

Drawing from Ephesians 4:30–31, RT explains how easily the Holy Spirit is grieved by things like anger, slander, and bitterness—and how this directly affects your spiritual discernment.

RT closes with a reminder: if you want to hear God clearly, you must walk in forgiveness and keep the Holy Spirit ungrieved. This, more than anything, will preserve you from deception in the last days.
