Paris Reidhead emphasizes the significance of the witness of the Spirit in confirming one's relationship with God, drawing from John 3, 4, and 5 to illustrate how the Spirit assures believers of their eternal life. He stresses that true assurance comes from the Holy Spirit's testimony within us, rather than from external affirmations or mere profession of faith. Reidhead recounts personal experiences and historical insights, particularly from John Wesley, to highlight the importance of understanding the inner workings of the Spirit in awakening, convicting, and regenerating the human spirit. He encourages believers to guide those uncertain of their faith to seek the Spirit's confirmation through God's Word. Ultimately, the sermon underscores that only the Holy Spirit has the authority to affirm one's status as a child of God.

In this sermon, the speaker emphasizes the importance of the 40 days that Jesus spent on earth after His resurrection. He explains that during this time, Jesus trained His disciples to shift their focus from external things to internal revelation, from the flesh to the Holy Spirit, and from the law to life. The speaker shares a personal anecdote about a turbulent airplane ride to illustrate the need for Christians to rise above fear and rely on the Holy Spirit. He concludes by urging the audience to prioritize their personal encounter with the Lord and the experience of being filled with the Holy Spirit.

John Nelson Darby explores the themes of righteousness and the nature of faith in his sermon on John's Gospel, emphasizing that the elder son in Luke 15, despite his adherence to righteousness, never entered the house. He highlights the importance of understanding divine truths through experience rather than mere definitions, and critiques the reliance on miracles for faith. Darby discusses the progression of Christ's ministry in the Gospel of John, noting the rejection of His words and works, and the significance of eternal life as central to His message. He also addresses the nature of rewards for believers and the transformative power of Christ in the lives of His followers.
