Alienation from

[soul man]

18 Having the understanding darkened, being alienated from the life of God through the ignorance that is in them, because of the blindness of their heart: - Ephesians 4:18.

-blindness of heart- is loving the wrong thing!

 

[Ferris Bueller]

I think blindness of heart is not having the eyes of your heart opened, either because God has never opened them, or because that person has rejected the knowledge of God when He did open them.
