Psalms 32:8 “I will instruct you and teach you in the way which you shall go:  I will guide you with mine eye.”     9. “Do not be like the horse, or as the mule, which have no understanding:  whose mouth must be held in with bit and bridle, or they will not come to you.”
The amount of pressure the instructor must apply to achieve the desired result tells a lot about the attitude of the one being instructed.
Remember when you were a child.  Maybe you were at church and you and a friend were talking or passing notes.  Your Dad could see you and catch your attention with his eye. With a very simple look, he could communicate great volumes of instruction and potential consequences.  He could literally “guide you with his eye.”
Maybe later in life, you were no longer willing to be guided by his eye.  Stronger measures had to be used.  In a sense, when you became mule headed, it took steel and lash to control you.  
The Holy Father wants you to know Him so well that His look will guide you.  How did you know ‘that’ look from your Dad?  He was your Dad, you knew him, you spent time with him.  You knew his ways, what pleased him or displeased him.  You had an intimate relationship with him.
In the same way you come to know your Holy Father.  You spend time with Him, in His Word, in prayer. You learn His ways. You come to know Him so well, so intimately, so closely, that He can guide gently, even with a look.   
And He will guide you in ways you never dreamed possible.
