T. Austin-Sparks explores the distinctive spiritual features of the Levites, emphasizing their unique relationship with the Cross, the Holy Spirit, and the Word of God. He distinguishes between spiritual and carnal Christians, highlighting that true spirituality is characterized by being governed by the Holy Spirit rather than self-interest. Sparks illustrates how spiritual people are sensitive to God's voice and the importance of aligning one's life with the Word of God, which serves as a mirror for self-examination. He concludes by discussing the Levites' inheritance, symbolizing spiritual governance and the call for believers to live under the Lord's authority. The sermon encourages Christians to seek a deeper, Spirit-led life that reflects God's will and purpose.
