What does the sermon say about the nature of man before the new birth?

According to the sermon, man by nature is spiritually dead and radically depraved. This inherent condition, as described in John 3:3, emphasizes that before being born again, individuals cannot see or comprehend spiritual realities. They live in a state of rebellion to God, oblivious to their need for salvation. The necessity of the new birth is rooted in the understanding that only through the Holy Spirit can one's eyes be opened to spiritual truth, allowing them to recognize their sinfulness and the grace of God offered through Christ.
