T. Austin-Sparks emphasizes the significance of spiritual vision in understanding God's purpose for His people, drawing parallels between the prophetic ministry in the Old Testament and the spiritual calling of the New Testament Church. He highlights that the question 'What seest thou?' is crucial for spiritual progress and understanding one's identity in Christ, as it governs assurance and direction in the believer's life. Sparks asserts that the Church represents the new Israel, embodying the spiritual principles of the Old Testament while moving towards a heavenly and eternal destiny. The urgency of this message calls for believers to seek spiritual sight and clarity in their walk with God, as their spiritual history and destiny are intertwined with their vision. Ultimately, the sermon challenges listeners to reflect on their understanding of God's current work and their role within it.
