G. Campbell Morgan addresses the contrasting movements in society regarding materialism and the search for spirituality, highlighting how materialistic views have permeated life outside the Church, leading many to live in practical atheism. He notes a significant revolt against materialism, evidenced by the rise of spiritualism and theosophy, yet warns against the extremes of denying matter altogether. Within the Church, a wave of rationalism threatens spiritual vitality, but there is also a revival of interest in the Holy Spirit's ministry, which is essential for true transformation. Morgan emphasizes the importance of grounding spiritual truths in Scripture to avoid the pitfalls of legalism and misinterpretation. He calls for a return to the Word of God as the ultimate guide to understanding the Spirit's work and the spiritual realm.
