What does the Bible say about the Gospel being hidden?

In 2 Corinthians 4:3-4, the Apostle Paul states, 'But if our gospel be hid, it is hid to them that are lost, in whom the God of this world hath blinded the minds of them which believe not.' This passage highlights that spiritual blindness is an active work of Satan, who seeks to prevent sinners from seeing the glory of God in the face of Christ. This condition of being lost is not merely a lack of understanding, but a profound spiritual deadness reflecting the depravity of humanity that fails to recognize the truth of the Gospel. It underscores the necessity of God’s sovereign grace to illuminate hearts, allowing them to perceive the beauty and truth of the Gospel.
