A.W. Tozer emphasizes the critical conflict in contemporary Christianity between objective intellectualism and the necessity of spiritual revelation through the Holy Spirit. He warns that an over-reliance on human intellect could lead to a lifeless orthodoxy, stripping the faith of its vital spiritual essence. Tozer argues that while understanding the faith is important, there are profound spiritual truths that transcend mere reason and require divine insight to grasp fully. He challenges the notion that all essential Christian truths can be comprehended solely through intellect, suggesting that such a belief may lead to rationalism and a diminished faith. The sermon calls for a balance between intellectual understanding and spiritual revelation to preserve the vitality of the Christian faith.
