2 Corinthians 4:3-4
But even if our gospel is veiled, it is veiled to those who are perishing, whose minds the god of this age has blinded, who do not believe, lest the light of the gospel of the glory of Christ, who is the image of God, should shine on them.
When we read the word blind; or blinded as we see it in the above Scripture, we tend to immediately think it refers to being unable to see.
However, the Hebrew concept of being blinded is to have your seeing bound to the negative.
You can see just fine, but you are passing all that you see through a filter of negativity.
As believers, if we allow our seeing to be bound to the negative, then we will fail to see the light of the Father shining in the midst of the current chaos of darkness.
