You have to ask yourself, for what purpose would God want people to remain disobedient to him?
There could be several plausible reasons:
1A. As an act of mercy: God feels if He opens their eyes to the truth in this satan influenced, corrupt and evil world, the person will not be strong enough to endure until the end (Matt 24:13) and possibly lose their salvation:
Heb 10:26 For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins,
Heb 6:4-6 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, 5 and have tasted the good word of God and the powers of the age to come, 6 if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame.
They will be much more receptive at the end of the millennium in the 2nd resurrection, after 1,000 years of living God's way and seeing the miraculous contrast between the earth they once knew and the one then. Satan will be out of the picture. The veil of deception lifted and their minds will be opened to the truth for the first time (Isa 25:7). Christ and the Saints will be there to greet them. To ease their fears and pinch them to convince them they are not dreaming.
B. Another plausible reason for God to deliberately blinding the majority of mankind is the simple fact there are only a finite number of leadership positions available during the millennium. He calls the church His "little flock" (luk 12:32). He also hints toward a small number in (Matt 22:14).Jud 1:14 alludes to a relatively small finite number (10,000). But other passages seem to indicate there could be more. The point is there is a relatively small, fixed number of leadership positions available in the kingdom. He cannot possibly call everyone now.
The truth is that he wants to save all mankind,
2. And I believe He does. Just not all in this age. Consider Christ's words: "For many are called, but few are chosen." (Mt 22:14). If God was trying to save the world in this age, shouldn't He have said, "For all are called, and many are chosen"?? After all, if He's trying to save them all, shouldn't He at least call them all? Also consider Mat 11:25: "At that time Jesus answered and said, "I thank You, Father, Lord of heaven and earth, that You have hidden these things from the wise and prudent and have revealed them to babes." If He was trying to save mankind now, why is He thanking the Father for "hiding" the truth to the wise and prudent of this age!! Could it be for the reason in point 1a??
so there must be some other reason why he does not 'draw them'...or as Paul says, 'God gives them a spirit of stupor' There is a question that need to be answered before a conclusion is made as to whether God is deliberately withholding some. The question is , Why are some drawn and shown the light, while others are kept in darkness?
3, Ask yourself this question while reading the list of verses in post
nine.
And Jesus gave a clear answer on this question. About the religious leaders and teachers of his days, he said this:
Matthew 13:14 and toward them the prophecy of Isaiah is having fulfillment, which says, ‘By hearing, YOU will hear but by no means get the sense of it; and, looking, YOU will look but by no means see. 15 For the heart of this people has grown unreceptive, and with their ears they have heard without response, and they have shut their eyes; that they might never see with their eyes and hear with their ears and get the sense of it with their hearts and turn back, and I heal them.
4. Notice the last part of vs 15. Christ states the reason why their eyes and ears are shut: so they will not convert and be healed. In the parallel, account Mark remarkably states so their sins will not be forgiven! Why wouldn't Christ want to heal and forgive them of their sins? Could it be for the reason in point 5?. Also notice what immediately follows these verses: The parable of the sower. Christ illustrates through the parable the different reactions of those who are called. Notice what He states about the first group:
Luk 8:12 Those by the wayside are the ones who hear; then the devil comes and takes away the word out of their hearts, lest they should believe and be saved.
We both know God controls satan's actions. If God wanted every person saved in this life, He would not allow the devil to remove the word that was sown in their hearts. Just like He commanded the devil not to hurt or later kill Job, He could command him not to remove the sown word. Why doesn't God stop him if He wants everyone saved? The only logical answer is that He doesn't want them to believe and be saved, yet... Just like many other passages indicate!!!
So it is not because God deliberately prevents a person from seeing and understanding....it is because some people are 'unreceptive' to Gods word. They prefer their own understanding and will not allow themselves to be corrected. When Jesus taught those religious leaders, they didn't all respond positively...rather they gnashed their teeth at him. How can God draw people who don't allow their heart to be moved by the truth of Gods word?
5. Has it ever occurred to you that God hardened most of Israel's, as well as the religious leaders hearts, just like Pharaoh's, so His plan of salvation can move forward? If the religious leaders and Israel would have believed Christ at His first coming, they would have never killed Him and we'd have no Savior!!!
They are hard hearted toward God so he allows them to remain in their spiritually dark state. that is really what the above scriptures are telling us. Except for 2Corinthians4...that 'god of this system' is actually Satan the devil, not Almighty God .
6. Scripture reveals who does most of the hardening:
Rom 9:18 Therefore He has mercy on whom He wills, and whom He wills He hardens.
Exo_4:21 And the LORD said to Moses, "When you go back to Egypt, see that you do all those wonders before Pharaoh which I have put in your hand. But I will harden his heart, so that he will not let the people go.
Exo_7:3 And I will harden Pharaoh's heart, and multiply My signs and My wonders in the land of Egypt.
Exo 10:1 Now the LORD said to Moses, "Go in to Pharaoh; for I have hardened his heart and the hearts of his servants, [why?]that I may show these signs of Mine before him,
Exo 10:20 But the LORD hardened Pharaoh's heart, and he did not let the children of Israel go.
Exo 10:27 But the LORD hardened Pharaoh's heart, and he would not let them go.
Exo 11:10 So Moses and Aaron did all these wonders before Pharaoh; and the LORD hardened Pharaoh's heart, and he did not let the children of Israel go out of his land.
Exo 14:8 And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued the children of Israel; and the children of Israel went out with boldness.
Deu 2:30 "But Sihon king of Heshbon would not let us pass through, for the LORD your God hardened his spirit and made his heart obstinate, [why?]that He might deliver him into your hand, as it is this day. [fulfill His divine will]
Jos_11:20 For it was of the LORD to harden their hearts, that they should come against Israel in battle, that He might utterly destroy them, and that they might receive no mercy, but that He might destroy them, as the LORD had commanded Moses.
Isa 63:17 O LORD, why have You made us stray from Your ways, And hardened our heart from Your fear? Return for Your servants' sake, The tribes of Your inheritance.
