You are so spiritually blind that you are unable to even understand the verses which you cite:
"And even if our gospel is veiled, it is veiled to those who are perishing. The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God" (2 Cor.4:3-4).
Here we read that the god of this age has blinded the minds of unbelievers. And the purpose as to why he blinds them is
"so that they cannot see the light of the gospel." That means that those who are perishing did indeed at one time have the ability to see the light of the gospel.
After all, it is impossible to blind the minds of anyone to the truth of the gospel unless they have the ability in the first place to see the light of the gospel. The verb form of the word "blind" means to "make blind." It is impossible to "make blind" someone who is already blind.
The Calvinists must believe that the god of this age blinds those who are already blind! That idea is ridiculous.
Here the Lord Jesus illustrates that the word of God works in concert with the Spirit and that union results in life:
"It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life" (Jn.6:63).
We can understand that the gospel also works in concert with the Holy Spirit:
"For our gospel came not unto you in word only, but also in power, and in the Holy Spirit, and in much assurance" (1 Thess.1:5).
Even though Paul makes it plain that the gospel comes in much power and in the Holy Spirit the Calvinists say that it is powerless to save anyone unless a person is first "born again."
The Calvinists teach that a person is "born again" or "regenerated" prior to "faith" despite the fact that both Peter and James make it plain that being "born again" happens as a result of faith:
"Being born again, not of corruptible seed, but of incorruptible, by the word of God...And this is the word which by the gospel is preached unto you" (1 Pet.1:23,25).
"He chose to give us birth through the word of truth, that we might be a kind of firstfruits of all he created" (Jas.1:18).
