God knocks on the door of everyone’s hearts; many do not want to hear. It’s the free will He’s given every soul that either allows them to hear His voice within, or not hear.
None so blind as those who do not want to see. He never condemns anyone in that sense, we condemn ourselves. There is always the possibility of redemption, even up to the last minute of earthly life. Will everyone take that opportunity? It’s there for everyone.
That is my understanding.
One problem is that by living a life of grave sin and filling ones’ mind and heart with lies (via media, entertainment, propganda, porn etc) peoples’ hearts become harder and harder; basically calloused, so they cannot feel or hear the gentle voice and touch of God. That is very tragic.
Now that I can agree with instead of saying God did it to them...some people are just mean by nature and perverse by nature, I don't think God does it to them...Perhaps if he choose to he could change them, but that is different than saying He harden their hearts or blinded their eyes..God chooses whom he chooses...protects those he wishes to protect, and owes no one anything.
