I will lead the blind by ways they have not known,
along unfamiliar paths I will guide them;
I will turn the darkness into light before them
and make the rough places smooth.
These are the things I will do;
I will not forsake them.
But those who trust in idols,
who say to images, 'You are our gods,'
will be turned back in utter shame.
Israel Blind and Deaf
"Hear, you deaf;
look, you blind, and see!
— Isaiah 42:16-18

Listen carefully! God often whispers.
