So for the second time they called the man who had been blind, and they said to him,“Give
glory to God! We know that this man is a sinner.” He answered,  “I do not know whether
he is a sinner. One thing I do know, that though I was blind, now I see.” John 9:24-25

Having knowledge but lacking the power to express it clearly is no better than never having any ideas at all.
