Perception is not an attribute of God. His is the realm of knowledge. Yet He has created the Holy Spirit as the Mediator between perception and knowledge. Without this link with God, perception would have replaced knowledge forever in your mind. With this link with God, perception will become so changed and purified that it will lead to knowledge. That is its function as the Holy Spirit sees it. Therefore, that is its function in truth. In God you cannot see. Perception has no function in God, and does not exist. Yet in salvation, which is the undoing of what never was, perception has a mighty purpose. Made by the Son of God for an unholy purpose, it must become the means for the restoration of his holiness to his awareness. Perception has no meaning. Yet does the Holy Spirit give it a meaning very close to God's. Healed perception becomes the means by which the Son of God forgives his brother, and thus forgives himself.
You cannot see apart from God because you cannot be apart from God. Whatever you do you do in Him, because whatever you think, you think with His Mind. If vision is real, and it is real to the extent to which it shares the Holy Spirit's purpose, then you cannot see apart from God.
