T. Austin-Sparks emphasizes that God's people are a princely people, reflecting the character of the Lord Jesus. He explains that true princeliness is marked by spiritual dignity, stature, and wealth, which are derived from a deep appreciation of the Cross. The sermon highlights that princeliness is not about outward display but about a humble, generous spirit that seeks to serve beyond mere obligation. Sparks encourages believers to embody this princely nature in all aspects of life, demonstrating the grandeur of Christ through their actions and attitudes. Ultimately, he calls for a spontaneous and heartfelt expression of worship and service that honors the significance of the Cross.
