God's sovereignty extends over both physical sight and spiritual understanding, and at times, He exercises His prerogative to blind as part of His purpose. He declares in Exodus 4:11 that He is the source of human abilities, including sight and blindness, affirming His control over both the physical and spiritual realms. As Isaiah 45:7 states, He forms light and creates darkness, makes peace and creates calamity, showing that His actions are not limited by human concepts of Him. In biblical accounts, God has used His servants, such as angels and humans, to blind those who oppose Him. For instance, He blinded the violent Sodomites through angels sent to deliver Lot, and at Elisha's request, He temporarily blinded the Syrian army. Similarly, Christ Himself struck Paul blind on the road to Damascus, symbolizing the spiritual blindness in which Paul walked prior to that moment. Through such acts, God demonstrates His authority over sight and understanding. God also warns of spiritual blindness as a consequence of disobedience. In Deuteronomy 28:15, He promises madness, blindness, and confusion of heart to the Israelites for failing to observe His commandments, rendering them unable to discern or find solutions apart from Him. This mental blindness exacerbates their plight, as they cannot even recognize the cause of their suffering or the need for repentance. In the New Testament, Jesus affirms this divine prerogative in John 9:39, stating that He came into the world for judgment, to make some see and others blind. This reflects God's purpose in both opening eyes and concealing understanding, as Solomon notes in Proverbs 25:2 that it is God's glory to conceal a matter. God's willingness to blind, whether physically or spiritually, underscores His supreme authority, even when such actions challenge human expectations of His nature.

God's blinding is a profound and often unsettling aspect of His sovereignty, demonstrating His authority over both physical and spiritual sight. In Genesis 19:11, the angels sent by God struck the violent men of Sodom with blindness, rendering them unable to find the door, as a direct act of divine intervention. In Exodus 4:11, the Lord declares to Moses that He is the one who makes the mute, the deaf, the seeing, and the blind, affirming that all human capabilities, including blindness, are under His control. This extends beyond the physical to spiritual blindness, where understanding and perception are also subject to His will. In Deuteronomy 28:28-29, God promises to strike with madness, blindness, and confusion of heart as a curse for disobedience to His commandments, leaving individuals to grope in darkness, unable to comprehend their plight or find solutions like repentance. Similarly, in John 9:39, Jesus states that part of His mission is to make the seeing blind and to give sight to the blind, highlighting His role in determining spiritual vision. In John 12:37-40, it is revealed that God Himself blinded the eyes and hardened the hearts of many, preventing them from believing despite numerous signs, as their disobedience kept them under a curse. Romans 11:7-10 further illustrates this divine blinding, noting that while the elect obtained understanding, the rest of Israel were blinded by God, given a spirit of stupor and eyes that could not see, as a consequence of their disobedience. Romans 11:25 explains that this partial blindness of Israel persists until the fullness of the Gentiles is brought in, showing God's purposeful timing in His actions. Finally, in II Corinthians 4:4, there is a suggestion that the blinding of minds, often attributed elsewhere, may align with the consistent pattern of God's sovereignty over sight, as He withholds truth temporarily or as judgment, distinct from mere deception.

God's act of blinding is a consistent theme throughout Scripture, demonstrating His sovereignty over human understanding. God Himself takes responsibility for blinding, closing the eyes of individuals either as a judgment or out of mercy, according to His will. He hides and reveals truth as He moves His creation toward everlasting light, recognizing that without the necessary spiritual faculties, truth can be overwhelming and painful. Just as parents limit exposure to certain realities for their children, God limits what He holds His children responsible for, based on their capability. In His natural state, man cannot handle the knowledge and understanding that God possesses, so God opens or closes eyes as is appropriate. Scripture illustrates this in various instances, such as when God blinded Israel and hardened their hearts, as seen in Isaiah 6:9-10 and Isaiah 29:10-14. When Jesus came to His own, God withheld the blessing of recognition, so the Israelites could not see the Savior, not out of vindictiveness but as a testimony of their longstanding rejection. On the road to Emmaus, the eyes of the disciples were restrained until Jesus opened their understanding to see Him in the Scriptures. Romans 11:7-8 confirms that God gave Israel a spirit of stupor, eyes that should not see, and ears that should not hear, while the elect obtained understanding. In II Corinthians 4:3-4, the gospel is veiled to those who are perishing, whose minds the God of this age has blinded, preventing them from seeing the light of the gospel of the glory of Christ. This aligns with God's purpose, as He has concluded humanity in unbelief to show mercy upon all, as stated in Romans 11:32. God consigns some to disobedience now, so that He may show mercy later, opening the eyes of those He has blinded when the time is right. His sovereignty ensures that there is no contest for the souls of men, and only the elect are equipped by the Holy Spirit to understand the deep things, while others await their chance in the resurrection.
