Accepting the yoke of Gods sovereignty without the fear of God is not good.
If a person accepts the yoke of God’s sovereignty without fearing God, that means that he is undertaking to do God’s will only on a superficial level.
Therefore, he must have the fear of God as well.
Accepting the yoke of God’s sovereignty and fearing God correspond, respectively, to the garment of a tallit and to the tzitziyot (ritual fringes) on its corners.
The tallit is called the “garment of the King” because it draws down onto a person his acceptance of God’s sovereignty.
The tzitziyot, meanwhile, draw fear down onto the person.
Just as a tallit must possess tzitziyot, even though the tzitziyot are seemingly just tiny and insignificant threads, so too we require fear in addition to accepting the yoke of God’s sovereignty.
Although fear may be only a subtle and faint perception in the mind and heart, it is nevertheless required.
