εν οις ο θεος του αιωνος τουτου ετυφλωσεν τα νοηματα των απιστων εις το μη αυγασαι τον φωτισμον του ευαγγελιου της δοξης του χριστου ος εστιν εικων του θεου
en hois ho Theos tou aiōnos toutou etyphlōsen ta noēmata tōn apistōn eis to mē augasai ton phōtismon tou euangeliou tēs doxes tou Christou hos estin eikōn tou Theou
In whom The God of this age has blinded the thoughts of the unbelieving, so that the brightness of the gospel of The Glory, The Christ who is the image of God, should not dawn on them. (2 Cor 4.4)
Contrary to popular modern belief, ‘The God of this age’, (ho Theos tou aiōnos toutou), actually pertains to Jesus Christ and NOT Satan, and provides yet another potent scriptural proof for Jesus’ deity.
Outside of 2 Cor 4.4, the only other inflections of ‘blinded’ (i.e. etyphlōsen & etyphlōken), used in the entire NT, are located in John 12, and 1 John 2, and have Jesus as the subject:
• John 12 records that Isaiah wrote about Jesus, ‘The Arm of God’, ‘His Glory’ as blinding the thoughts of the unbelievers.
• 1 John 2 records without Jesus’ light, the unbelievers are blinded.
Contextually, the epithets contained within 2 Cor 4, including Theos, relate to Jesus…not to Satan.
No, nope, and nah, and...
You're off by a country mile, and then some.
Acts 26:15 And I said, Who art thou, Lord? And he said, I am Jesus whom thou persecutest. 26:16 But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee; 26:17 Delivering thee from the people, and from the Gentiles, unto whom now I send thee, 26:18 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.
From darkness to light - in other words, from the power of Satan unto God.
Power of Satan?
His will for all.
2 Timothy 2:24 And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, 2:25 In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth; 2:26 And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.
Where you went wrong is two-fold.
You failed to seek out not only all similar themes, but similar words possibly related to this issue.
The Greek ALONE will NOT cut it.
In Scripture, words like Lord, and lord, and God and god, and Prince and prince, and power and powers, and rulers and principalities and light and darkness, and so on, all center around closely related themes that help shed light on any one word, phrase, passage or passages, or theme, or themes, then turning to the Greek or what have one, alone can ever hope to thoroughly bring out.
Just as it is fool's gold to go either by "well, this, that, the other, makes/does not make sense to me..."
1 Corinthians 1:27 But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; 1:28 And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are: 1:29 That no flesh should glory in his presence.
Here, take a gander at the god / lord / prince / power of (the course of) this (fallen) world (system), Eph. 2:2.
Luke 4:5 And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time. 4:6 And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it. 4:7 If thou therefore wilt worship me, all shall be thine.
Acts 17: 11, 12.
