Freedomstands,
God is your God and my God.
Of course God curses. Blindness is a curse. But one should always look at oneself first. God does not have to really do anything for the soul shrinks to non-existence and then they will have a relapse. That is punishment enough. Perhaps they are reborn blind.
Even more sin it is to hurt a blessed person, because they have the favor of God. God protects those held dear.
That is indeed a message to be reflected upon.
Be well
