As soon as someone thinks they understand God, at that moment they begin to distance themselves from Him.
That's one reason God sends Manifestations and lets them live in a body for a few years: we humans get a lot more of the Message that way.
Yet, God's "Signature" is Everywhere.
"....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. And of all men, the most accomplished, the most distinguished and the most excellent are the Manifestations of the Sun of Truth."
