This glory which Paul describes, this is not a glory to come in the future.
This is a glory to be revealed in us today:
"Arise, shine; for thy light is come, and the glory of the LORD is risen upon thee. 2"For behold, darkness will cover the earth And deep darkness the peoples; But the LORD will rise upon you And His glory will appear upon you." (Isaiah 60: 1-2)
There will be no darkness in heaven, so this light speaks of our time on this earth:
"This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all." (1 John 1: 5)
"And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever." (Revelation 22: 5)
So, the Glory of God to be revealed in us will not be hid away or ineffectual in eternity with God our Father only.
This glory will break forth here and now.
"To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory." (Colossians 1: 27)
"Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God." (1 Peter 1: 21)
"Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world." (1 John 4: 17)
Any suffering we endure is a sign of our sonship in Christ before God our Father too:
"Though he were a Son, yet learned he obedience by the things which he suffered" (Hebrews 5:8)
"And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:
6For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth." (Hebrews 12: 5-6)
We are partakers of God's holiness (Hebrews 12: 10) and the less of ourselves, our flesh we depend on, and the more of His Spirit shines in us, the greater Jesus' glory is manifested in our lives.
