A.W. Tozer addresses the dual dangers of prosperity and adversity in the Christian life, emphasizing that both can lead to spiritual peril. He illustrates how prosperity can foster independence from God, as seen in the history of Israel, while adversity can either strengthen faith or lead to despair. Tozer encourages believers to remain vigilant, detached from earthly possessions, and to view themselves as pilgrims on a journey to their eternal home. He offers practical advice on how to navigate these dangers by thanking God, sharing generously, and walking circumspectly. Ultimately, he reminds the congregation that true security lies in trusting God as their Rock and Fortress.
