"What is the glory of God?"
 Answer:  The glory of God is the beauty of His spirit. It is not an aesthetic  beauty or a material beauty, but it is the beauty that emanates from His  character, from all that He is. James 1:10  calls on a rich man to “glory in his humiliation,” indicating a glory  that does not mean riches or power or material beauty. This glory can  crown man or fill the earth. It is seen within man and in the earth, but  it is not of them; it is of God. The glory of man is the beauty of  man’s spirit, which is fallible and eventually passes away, and is  therefore humiliating—as the verse tells us. But the glory of God, which  is manifested in all His attributes together, never passes away. It is  eternal.
Isaiah 43:7  says that God created us for His glory. In context with the other  verses, it can be said that man “glorifies” God because through man,  God’s glory can be seen in things such as love, music, heroism and so  forth—things belonging to God that we are carrying “in jars of clay” (2 Corinthians 4:7).  We are the vessels which “contain” His glory. All the things we are  able to do and to be find their source in Him. God interacts with nature  in the same way. Nature exhibits His glory. His glory is revealed to  man’s mind through the material world in many ways, and often in  different ways to different people. One person may be thrilled by the  sight of the mountains, and another person may love the beauty of the  sea. But that which is behind them both (God’s glory) speaks to both  people and connects them to God. In this way, God is able to reveal  Himself to all men, no matter their race, heritage or location. As Psalm 19:1-4  says, “The heavens are telling of the glory of God and their expanse is  declaring the work of His hands; day to day pours forth speech, and  night to night reveals knowledge. There is no speech, nor are there  words; their voice is not heard. Their line has gone out through all the  earth, and their utterances to the end of the world.”
Psalm 73:24  calls heaven itself “glory.” It used to be common to hear Christians  talk of death as being “received unto glory,” which is a phrase borrowed  from this Psalm. When the Christian dies, he will be taken into God’s  presence, and in His presence will be naturally surrounded by God’s  glory. We will be taken to the place where God’s beauty literally  resides—the beauty of His Spirit will be there, because He will be  there. Again, the beauty of His Spirit (or the essence of Who He Is) is  His “glory.” In that place, His glory will not need to come through man  or nature, rather it will be seen clearly, just as 1 Corinthians 13:12  says, “For now we see in a mirror dimly, but then face to face; now I  know in part, but then I shall know fully just as I also have been fully  known.”
In the human/earthly sense, glory is a beauty or vibrancy that rests upon the material of the earth (Psalm 37:20, Psalm 49:17),  and in that sense, it fades. But the reason it fades is that material  things do not last. They die and wither, but the glory that is in them  belongs to God, and returns to Him when death or decay takes the  material. Think of the rich man mentioned earlier. The verse says, “The  rich man is to glory in his humiliation, because like flowering grass he  will pass away.” What does this mean? The verse is admonishing the rich  man to realize that his wealth and power and beauty come from God, and  to be humbled by the realization that it is God who makes him what he  is, and gives him all he has. And the knowledge that he will pass away  like the grass is what will bring him to the realization that God is the  one from whom glory comes. God’s glory is the source, the wellspring  from which all smaller glories run.
Since God is the one from whom glory comes, He will not let stand the  assertion that glory comes from man or from the idols of man or from  nature. In Isaiah 42:8, we see an example of God’s jealousy over His glory. This jealousy for His own glory is what Paul is talking about in Romans 1:21-25  when he speaks of the ways people worship the creature rather than the  Creator. In other words, they looked at the object through which God’s  glory was coming, and, instead of giving God the credit for it, they  worshiped that animal or tree or man as if the beauty it possessed  originated from within itself. This is the very heart of idolatry and is  a very common occurrence. Everyone who has ever lived has committed  this error at one time or another. We have all “exchanged” the glory of  God in favor of the “glory of man.”
 This is the mistake many people continue to make: trusting in earthly  things, earthly relationships, their own powers or talents or beauty, or  the goodness they see in others. But when these things fade and fail as  they will inevitably do (being only temporary carriers of the greater  glory), these people despair. What we all need to realize is that God’s  glory is constant, and as we journey through life we will see it  manifest here and there, in this person or that forest, or in a story of  love or heroism, fiction or non-fiction, or our own personal lives. But  it all goes back to God in the end. And the only way to God is through  His Son, Jesus Christ. We will find the very source of all beauty in  Him, in heaven, if we are in Christ. Nothing will be lost to us. All  those things that faded in life we will find again in Him.
