In this sermon, the speaker emphasizes the privilege of being expendable for the Lord Jesus and allowing Him to work in His own way and time. The sermon highlights the power of God's intervention, as seen in the story of Paul and Silas being freed from prison by an earthquake. The angel of the Lord instructs them to go and speak in the temple, sharing "all the words of this life," which refers to the gospel message. The sermon also emphasizes that Jesus came to give life and restore what was lost in Adam, and that believers are called to be obedient to the heavenly vision and go where God sends them.

T. Austin-Sparks emphasizes the critical role of spiritual intelligence in overcoming the tactics of Satan, who seeks to keep humanity in ignorance and blindness. He illustrates that just as military intelligence is vital for victory in warfare, spiritual enlightenment is essential for believers to recognize and counter the enemy's schemes. Sparks also discusses the importance of diversity within the body of Christ, where each member has a unique role that contributes to the overall mission, highlighting that the Holy Spirit equips every believer for their specific function. He concludes that a sense of vocation and service is crucial for spiritual growth and fulfillment, urging believers to actively engage in their calling.

T. Austin-Sparks preaches on the intensifying conflict and widening division in John 9, where the man born blind represents spiritual sight and revelation against the backdrop of tradition and historic systems. The focal point of the controversy is 'Light through life', highlighting the difference between acknowledging our spiritual blindness and self-sufficiency. The sermon emphasizes how our natural limitations and handicaps are opportunities for God's sovereignty to work through us, as seen in the examples of Moses and Jeremiah. It concludes with the importance of spiritual illumination causing division and opposition, yet being a precious gift that leads to true discipleship.

T. Austin-Sparks preaches about the significance of Christ as the Son of Man, emphasizing His role as the arch-type of a new humanity and the Redeemer-Kinsman. Through Christ, God has initiated a new order of mankind, free from the sinful nature that estranges humanity from God. The humanity of Jesus represents an incorruptible life that satisfies God's holiness, providing the power of redemption. As the Redeemer-Kinsman, Christ has the right, power, liberty, and willingness to redeem and unite His people to Himself in a sacred bond, symbolized by the marriage between the Church and the Lord.
