Jessie Penn-Lewis warns against the dangerous trend of conflating psychical experiences with spiritual truths, emphasizing that many contemporary teachings misappropriate sacred elements of the Gospel for demonic doctrines. She highlights the blasphemies against God that arise when the Lord's Table is treated as a source of psychic power rather than a sacred remembrance of Christ's sacrifice. Penn-Lewis stresses the distinction between the soul and spirit, asserting that psychic powers stem from fallen nature and are not of God. She calls believers to reject the cultivation of the psychic life and instead embrace the Cross of Christ, which leads to true spiritual life. Ultimately, she urges the church to discern the source of power and to ensure it aligns with the teachings of Scripture.
