There is the unbeliever, who has been blinded by the devil, """IN Whom.... the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.""
I do not believe the verse is speaking about Satan being the God of this world. Satan is called the Prince of the world but not the God of it. Certainly much of the world worships Satan in one form or another but in order to know whom is being spoken of we simply have to use the context:
2 Corinthians 4:4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
So who was it that "blinded the minds of them which believe not"?
It was God.
Joh 12:38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord, who hath believed our report? and to whom hath the arm of the Lord been revealed?
Joh 12:39
Therefore they could not believe, because that Esaias said again,
Joh 12:40
He (God) hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
The HE here is God and this is very similar language. God blinded them so they could not convert and be healed! Isn't that what the other verse is saying? Also note that in both scriptures the people being blinded didn't believe prior to the blinding:
"blinded the minds of them which believe not"
"Therefore they could not believe" "He (God) hath blinded their eyes"
Same God doing the blinding and same people being blinded.
Romans 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded
Romans 11:8 (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear) unto this day.
Some will say it's a little "g" on god so that means its not God. Not so. There are no capitals in the manuscripts. The small g is purely the translators opinion. It is not fact nor is it done because of any small letter in the manuscripts.
While Satan can be considered a false god of this world, he simply isn't the one being spoken of because it is God which blinds so people cannot convert to Christ and be healed.
I have removed capitals because they don't exist in the manuscripts and I don't want the concept of capitals interfering with understanding what is being said or providing a bias. I also removed the verse numbers so it can be read naturally as Paul intended.
2Co 3:11 through 2Co 4:15
for if that which is done away was glorious, much more that which remaineth is glorious.
seeing then that we have such hope, we use great plainness of speech:
and not as moses, which put a vail over his face, that the children of israel could not stedfastly look to the end of that which is abolished:
but their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in christ.
but even unto this day, when moses is read,
the vail is upon their heart.
*God blinded these people and even today that blindness remains.
nevertheless when it shall turn to the lord, the vail shall be taken away. now the lord is that spirit: and where the spirit of the lord is, there is liberty.
but we all, with open face beholding as in a glass the glory of the lord, are changed into the same image from glory to glory, even as by the spirit of the lord.
therefore seeing we have this ministry, as we have received mercy, we faint not;
but have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of god deceitfully; but by manifestation of the truth commending ourselves to every man's conscience in the sight of god. but if our gospel be hid,
it is hid to them that are lost:
*Context matters and the context here is regarding God blinding Israel. Was Israel lost? Was the Gospel hidden from them? Yes. Jer_50:6 "My people hath been lost sheep" . Who the lost are here, the ones that the gospel is hidden from is all here in this letter. Israel.
in whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of christ, who is the image of god, should shine unto them.
*Keeping context sound, there has been no abrupt change inserting satan into this dialogue. The subject is Israel, the ones who are lost, the ones God blinded, and the ones the Gospel was hidden from. "god" here is the same "god" Paul has been speaking of and the ones being blinded by this "god" are the same ones Paul just mentioned literally a handful of sentences before! Israel.
for we preach not ourselves, but christ jesus the lord; and ourselves your servants for jesus' sake.
for god, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of god in the face of jesus christ.
*Contexually this is the SAME GOD as the one above, " the god of this world hath blinded the minds of them which believe not".
but we have this treasure in earthen vessels, that the excellency of the power may be of god, and not of us.
we are troubled on every side, yet not distressed; we are perplexed, but not in despair;
persecuted, but not forsaken; cast down, but not destroyed;
always bearing about in the body the dying of the lord jesus, that the life also of jesus might be made manifest in our body.
for we which live are alway delivered unto death for jesus' sake, that the life also of jesus might be made manifest in our mortal flesh.
so then death worketh in us, but life in you.
we having the same spirit of faith, according as it is written, i believed, and therefore have i spoken; we also believe, and therefore speak;
knowing that he which raised up the lord jesus shall raise up us also by jesus, and shall present us with you.
for all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of god.
*same God being spoken of, same people blinded.
Guess what? This is the same thing Paul mentioned in the book of Romans earlier:
Rom 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits;
that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
And that came from something Christ spoke of:
Joh 12:38 That the saying of Esaias the prophet might be fulfilled, which he spake, Lord,
who hath believed our report? and to whom hath the arm of the Lord been revealed?
Who hath believed their report? Not Israel, who was blinded. Not Israel, because that report was the Gospel and it was hidden from them, 2Co_3:14 and 2Co_4:3-4
Joh 12:39
Therefore they could not believe, because that Esaias said again,
They could not believe because God blinded them and hid the Gospel from them.
Joh 12:40
He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and
I should heal them.
He blinded their eyes and hardened their heart. Why? So they could not see nor understand and be converted and healed by God.
1Pe 2:21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
1Pe 2:22 Who did no sin, neither was guile found in his mouth:
1Pe 2:23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
1Pe 2:24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness:
by whose stripes ye were healed.
Why blind them to keep them from being healed and finding that glorious light of Christ? It wasn't time for that yet.
What John 12:40 says is the same thing that 2 Corinthians 4:4 says:
God "hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them."
God "hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them."
1. "hath blinded the minds of them which believe not"
1. "hath blinded their eyes, and hardened their heart"
2. "lest the light of the glorious gospel of Christ" "should shine unto them"
2. "they should not see with their eyes, nor understand with their heart, and be converted" nor healed.
Having your eyes "blinded" and your heart "hardened" is the same thing as having your "mind" blinded.
"converting and being healed" is the same thing as receiving "the light of the glorious gospel of Christ".
