Why do some people reject the Gospel despite knowing Scripture?

The sermon highlights that not all who have access to Scripture or knowledge of God will receive the Gospel. This is because true understanding and belief hinge on the work of the Holy Spirit, who must awaken individuals to recognize their need for Christ. Many may claim to know God or adhere to religious practices but remain spiritually blind because they have not been regenerated by the Spirit. This reflects the nature of humanity's fallen state and the necessity of God's sovereign grace in choosing whom to save. Ultimately, salvation is a work of God, initiated by the Holy Spirit, who opens blind eyes to see the truth of the Gospel.
