To give glory to God is to know Who He is. He reveals Himself in His glory to you. You acknowledge His glory back unto Him. Your worship is collective. All the saints and angels bear witness to your praise. If you haven’t seen, then maybe you have heard? That’s fine. Your worship is noetic. The glory of the Lord will enter your soul through your spiritual senses. It will permeate your highest intellect, your nous. You magnify His appearance in yourself. Don’t turn your back. Don’t stop looking. Worship is instant, immediate, a single process, a fully functional expression of a man’s telos. Worship is the purpose of a man’s formal design. When that happens, a man’s telos shines in the luminance, in the phanos of the Lord’s glory. When a man lacks worship, and claims that he perceives nothing of God, it is because he insists that the reflection of God’s glory in the darkness of his intellect is just a phantasm. For such a man, this fantastic self-object becomes his only point of reference, an idol in his imagination. Now he will guard his idol unto death. Such men refuse to take their spiritual senses seriously. They make this choice in the pride of their limited, human, speculative, abstract reasoning. Their fault is not in their senses as they claim, but in their intellect and will. But worship is not an epistemological matter. Worship requires δοκεω, an action of the mind and heart of processing information into understanding and choices. This information is apparent to our senses. It is perceptual. Worship begins as a matter of seeming.
A clean mind is not an empty mind. Our mind can never be entirely empty of thoughts, feelings and ideas. Curating one’s mind requires experience and discernment. Our mind (or dianous) is the instrumental part of our psyche. The highest part of our psyche is our intellect (or nous). It is through our nous that we perceive and experience divine nature. Our nous manages our dianous. When our nous is illumined by the divine grace of the Holy Spirit, then we manage our minds well. Our nous is clarified by divine grace in worship and prayerful attention. When that happens, then we are able to manage ourselves with discernment and discretion in the field of our mental activity. Our choices regarding what sensations to experience, activities to engage in, ideas to reflect upon, emotional responses to make, etc., will all become morally virtuous when guided by a godly light in our nous. Then our mind will be a well-functioning tool, a cleaned instrument.
