The sermon explores the necessity of spiritual rebirth, emphasizing that human intellect and education are insufficient for understanding divine truths. Drawing from Old Testament parallels, it highlights the importance of faith, the revelation of Christ as the Son of Man, and the believer's benefit from Christ's sacrifice and exaltation. Ultimately, it calls for a lively faith rooted in a grateful heart, a reliance on the Spirit's witness, and a confident embrace of Christ's promises and ongoing intercession, encouraging a life reflecting God's grace and anticipating His return.
