Now every living thing can display the names and attributes of God but just some of them and at a low level. But it is the human being that has the potential to display all of the names and attributes of God at the highest level. Basically the human being is the greatest and most perfect of all of God's creations.
Baha'u'llah says in the Kitáb-i-íqán:
"From that which hath been said it becometh evident that all things, in their inmost reality, testify to the revelation of the names and attributes of God within them. Each according to its capacity, indicateth, and is expressive of, the knowledge of God. So potent and universal is this revelation, that it hath encompassed all things, visible and invisible. Thus hath He revealed: “Hath aught else save Thee a power of revelation which is not possessed by Thee, that it could have manifested Thee? Blind is the eye which doth not perceive Thee.” Likewise, hath the eternal King spoken: “No thing have I perceived, except that I perceived God within it, God before it, or God after it.” Also in the tradition of Kumayl it is written: “Behold, a light hath shone forth out of the Morn of eternity, and lo! its waves have penetrated the inmost reality of all men.” Man, the noblest and most perfect of all created things, excelleth them all in the intensity of this revelation, and is a fuller expression of its glory".
