Everything...I can only share scripture with you I can NOT help you understand it.
On Holy Images Saint John of Damascus,
Now, as we are talking of images and worship, let us analyse the exact meaning of each. An image is a likeness of the original with a certain difference, for it is not an exact reproduction of the original. Thus, the Son is the living, substantial, unchangeable Image of the invisible God, bearing in Himself the whole Father, being in all things equal to Him, differing only in being begotten by the Father, who is the Begetter; the Son is begotten. The Father does not proceed from the Son, but the Son from the Father. It is through the Son, though not after Him, that He is what He is, the Father who generates. In God, too, there are representations and images of His future acts,-that is to say, His counsel from all eternity, which is ever unchangeable. That which is divine is immutable; there is no change in Him, nor shadow of change. Blessed Denis, [note: the Pseudo-Dionysius] who has made divine things in God's presence his study, says that these representations and images arc marked out beforehand. In His counsels, God has noted and settled all that He would do, the unchanging future events before tbey came to pass. In the same way, a man who wished to build a house would first make and think out a plan. Again, visible things are images of invisible and intangible things, on which they throw a faint light. Holy Scripture clothes in figure God and the angels, and the same holy man (Blessed Denis) explains why. When sensible things sufficiently render what is beyond sense, and give a form to what is intangible, a medium would be reckoned imperfect according to our standard, if it did not fully represent material vision, or if it required effort of mind. If, therefore, Holy Scripture, providing for our need, ever putting before us what is intangible, clothes it in flesh, does it not make an image of what is thus invested with our nature, and brought to the level of our desires, yet invisible? A certain conception through the senses thus takes place in the brain, which was not there before, and is transmitted to the judicial faculty, and added to the mental store. Gregory, who is so eloquent about God, says that the mind, which is set upon getting beyond corporeal things, , is incapable of doing it. For the invisible things of God since the creation of the world are made visible through images. We see images in creation which remind us faintly of God, as when, for instance, we speak of the holy and adorable Trinity, imaged by the sun, or light, or burning rays, or by a running fountain, or a full river, or by the mind, speech, or the spirit within us, or by a rose tree, or a sprouting flower, or a sweet fragrance. Again, an image is expressive of something in the future, mystically shadowing forth what is to happen. For instance, the ark represents the image of Our Lady, Mother of God, so does the staff and the earthen jar. The serpent brings before us Him who vanquished on the Cross the bite of the original serpent; the sea, -water, and the cloud the grace of baptism.
I have that all in one Picture. It offends the Jews and Muslims though LOL.
