Fear should always serve as an incentive, a reason to turn to the Creator. After all, the Creator gives us unpleasant sensations in order to turn to the source they come from.
And why do we get blows from the source? Because we cannot properly connect with Him face to face, we turn our back to Him.
From our side it is Kelim of reception and from the side of the Creator, Kelim of bestowal. He turns to us with his Kelim of bestowal, but we do not want to accept Him because we are only ready to receive egoistically for now. Therefore, we feel His address as a blow with a stick instead of a carrot. That is the whole point.
