What does the Bible say about God's sovereignty over delusions?

In Isaiah 66:4, we see a clear declaration that God will choose the delusions of those who do not respond to His call. This illustrates God's sovereign authority in choosing how He deals with humanity, emphasizing that He has control over the hearts and minds of men. It is a profound truth that God does not merely allow people to go astray but actively turns them over to their delusions when they reject the truth of His Word. This concept aligns with other scriptures that affirm God's sovereignty and His ability to harden hearts or soften them according to His divine purposes, thus reinforcing that God is fully in control of all things, including spiritual blindness.
