In fact, their minds were grown hard and calloused [they had become dull and had lost the power of understanding]; for until this present day, when the Old Testament (the old covenant) is being read, that same veil still lies [on their hearts], not being lifted [to reveal] that in Christ it is made void and done away.

For the god of this world has blinded the unbelievers’ minds [that they should not discern the truth], preventing them from seeing the illuminating light of the Gospel of the glory of Christ (the Messiah), Who is the Image and Likeness of God.
