Ps 4Answer me when I call to you,
O my righteous God.
Give me relief from my distress;
be merciful to me and hear my prayer.
How long, O men, will you turn my glory into shame?
How long will you love delusions and seek false gods ?
Selah
When the Psalmist describes man as the glory of God , he is describing the man who ruled  the garden of God. God made man to glorify Himself by ruling the creation. In the garden man was able to do what he wanted because he had no corruption or opposition. The more he obeyed the greater freedom he enjoyed and the more he was blessed by God. He not only was pleased with his work but he enjoyed perfect fellowship with Eve. In continually being successful the opportunities for more success expanded and mans confidence grew.

 But when sin entered the world, man was opposed by corruption, sin and the curse. Now instead of perfect unity expressed in the language, sin brought in a new language of rebellion and man bringing glory to himself by becoming his own god. Instead of being perfect so that he created freedom and opportunity for eve , man began to take the opportunity and the freedom to himself. When sin entered God had to cursed  the language of destruction.  This is why the Psalmist complains about How long, O men, will you turn my glory into shame? How long will you love delusions and seek false gods?The Psalmist has learned to oppose the destructive language by cursing the wicked. If man was made to glorify God by being successful in ruling the earth then the only way to restore mans authority is  to give him eternal decrees in curses so  that he can return be made complete. Before the fall God made man with eternal purposes. We are only satisfied when we fulfill these eternal desires.

But the problem God had to address was giving man these eternal desires without eradicating sin. God had to give us eternal pronouncements that cannot be in our control. God had to speak so that we can only repeat what He says. God had to give us enough eternal language to satisfy our eternal desires. So God restored our eternal desires by giving us His axioms that are contained in His desires. By memorizing and speaking them our desires are consumed by Gods desires. This is why God decreed that we will rule over all the earth as a present promise. So when the wicked turn Gods glory into shame they are redefining the axioms and opposing God himself. So the Psalmist is using the pronoun as God speaking How long, O men, will you turn MY glory into shame?
How long will you love delusions and seek false gods ? My glory is My desires in the law, covenants, curses, statutes, promises, decrees and blessings. The Psalmist is using the axioms to argue for his petition. When man opposes God he opposes the Psalmist. When he opposes God he becomes his own god.
