2 Corinthians 4:3-4 But if our Gospel is veiled, it is veiled to those who are perishing. In their case, the god of this age has blinded the minds of the unbelievers so they cannot see the light of the gospel of the glory of Christ, who is the image of God.

 The god of this world is Satan, who controls the ideologies, opinions, hopes, aims, goals, and views that are currently strong in the world. He is behind the world’s philosophy, and ideologies. His attack on humanity, is to blind and delude the lost, so they cannot see the light of the Gospel. People apart from Jesus are dead in their trespasses and sins, veiled from the truth, haters of light and lovers of darkness.

 Ephesians 2:1-3 And you were dead in your trespasses and sins in which you previously walked according to the ways of this world, according to the ruler who exercises authority over the lower heavens, the spirit now working in the disobedient. We too all previously lived among them in our fleshly desires, carrying out the inclinations of our flesh and thoughts, and we were by nature children under wrath as the others were also.

People apart from Jesus cannot think rightly about spiritual truth because their minds are depraved. In a popular interview posted on YouTube, scientist Leonard Mlodinow, who co-authored The Grand Design with Stephen Hawking, declared, “Science shows that God is not necessary to explain the universe.” He also adds, “I find it very hard to see how people could believe in the Bible.” Then Mlodinow gave this very surprising answer to another question on the same interview:

I tend not to believe things that there is no evidence for. But it is not always true. I do believe, for instance, in aliens. I believe that there is life on other planets, and I think there is no evidence for that. We don’t understand the origin of life on Earth well enough to say how probable it is that on another star life would form. But in my heart for some reason I find myself believing that.

Christian apologist William Lane Craig commented on this quote: That is really bizarre, isn’t it? That he believes in aliens even though he says he has no evidence for it, but he just finds he believes in his heart that extraterrestrial life exists. But he doesn’t apparently find it in his heart to think that God exists the way many people do. If he thinks he is rational in believing in aliens, why isn’t it rational to believe in God?

It is quite possible to be an intellectual genius, and a spiritual fool. We should pray diligently. We should also communicate articulately. Then trust God to open the eyes of unbelievers, so they can see the light of the Gospel of the glory of Christ.
