2 Corinthians 4:2-4 2 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. 3 But if our gospel be hid, it is hid to them that are lost: 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. Interlinear=If yet and it is having been covered the well message of us in the ones being destroyed it is covered Thayer/Strongs Kalypto = to hide, veil, to hinder the knowledge of a thing Akin to Lepto=to steal, take away i.e. to take away with stealth. And Akin to krypto=to hide, conceal, to be hid, escape notice, metaph. To conceal (that it may not become known). So who hides and conceals the gospel from those who don't believe? As verse 4 states: 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. First who is the one who hides and deceives mankind, we would have to say it is the devil, he is the great deceiver. Many have their focus on the things of this world and the great deceiver blinds their eyes to the Gospel. He conceaqls many things from them and with Eve he told a lie about what God stated to Adam about eating from the tree of the knowledge of good and evil, he deceived her. So back to the question who is the god of this world that has blinded the minds of them which believe not?
