Every word is created by man to express some specific meaning/experience/feelings/perception/realization,hence power of words is limited .With these words GOD can not be described/defined/reached because GOD is eternal,boundless,infinite,measureless.
With these limited meaning of words all religious books are written, that is why these books are unable to describe/define GOD's form and HIS existence. These books are imperfect and GOD is PERFECT.
Human perceptions are unlimited/infinite .Every perception can not be expressed by existing words, for example sugar is sweet and honey is also sweet but there is very minute difference in their sweetness.There is no word to describe that difference.Exactly the same way word-power can not exactly define or describe GOD.It revolve round GOD, can not reach GOD. God is beyond word power. The day man is able to create the word to define/reach GOD,Man will reach GODNESS.
