When I read that scripture in 2 Corinthians I cried, because it describes my experience perfectly, so no, it isn't just the words of Paul, but my own personal experience.
Carmen's mind was blinded, but the veil was taken away in Christ. For so long when she read the scriptures and talked (argued) with Christians a veil lie on her heart. But then one day she said "Lord, I will listen only to you." and the veil was taken away. Now the Lord is the Spirit, and the Spirit is in her heart giving her true freedom for the first time in her life.
