How could God lose glory as described in John 17:5 ?

In this verse Jesus asks God the Father to glorify them both with the same glory they had before the earth was created. This implies that they had lost glory after the earth was created. Knowing God from scripture and being taught all spiritual things by the Holy spirit (John 14:26 and 16:13) in faith, I offer this reasoning: We know God The Father is completely holy and would desire perfection in all that He does. He would even extend his responsibility to creating all good things. Recall that when the earth and its inhabitants were created that God inspected His works and certified that they were good. But, since mankind was created with personal wills and the ability to choose good and evil, Michael and 1/3 of heaven’s created angels were tempted by pride to consider themselves equal to God and in competition with God for His creation. Big mistake! Then Adam and Eve chose sin over God’s will and were doomed to death and struggle on earth.

Even though “The Law” was given to guide the Old Testament peoples, we are told they could not achieve salvation through the Law. People were imperfect and could not comply with all God’s given standards. Mankind was doomed to fail and could not achieve an eternal relationship, as God desired, with Him. God wanted more. He had failed in His own standard. It was necessary that Christ, who had created all, come to earth to correct the problem. Christ overcame Lucifer’s temptations after His 40 day preparation fast in the desert. He was not tempted in the same way that Satan was and His rebukes to Satan’s temptations chose the Father’s will every time. This was Christ’s first major battle victory. Recall, that as we obey The Father’s will here on earth, there are also equal victories gained in Heaven’s spiritual domain. The last battle was won on the cross when Christ took up His own life and conquered death. Now His sacrificial blood could cover those that accepted and believed in Him. God had overcome Lucifer and had created a means to achieve His early intent for a continuous relationship with His creation. Heaven was once again holy with the evil angels thrown out. Men and women could choose their eternal destination and have hope to achieve it. God was again perfect and totally worthy of praise and glory.
