For Paul there is another thing that emanates from right standing before God: we rejoice in hope of the glory of God.
Sinners who acquire the right to live, will also be restored. Having been saved from the world over which God’s wrath is revealed unto death, they will share in the glory of God. Together with their justification, they can also expect glorification. Once you have gained peace with God, you may look forward to paradise!
What people missing in this world is proximity to God’s glory and the radiation of his justice. All of the Old Testament looks forward with longing to the return of that divine glory. The descent of the glory of the Lord on the tabernacle and later also on Solomon’s temple inspired the people with hope. The prophet Isaiah could see the temple being filled with the glory of the Lord, surrounded by his angels (Isaiah 6:1–13). The glory of God radiated around the shepherds in the fields when the angel announced the birth of Jesus. The appearance of Jesus himself on the mount of transfiguration changed as he became radiant. There are promising signs of future throughout history. The fullness of the divine glory will eventually fill the earth, just as the waters cover the sea. This is, of course, a terrifying prospect for those who refuse to honour God, but a most hopeful one for the Christians in Rome. Together with Paul, they can be joyful. The verb used by Paul here (kauchometha) translates as rejoice
indicates that they are not ashamed of this expectation. On the contrary, they openly proclaim and boast about it. This expectation is their pride and joy. As Gentiles they used to have all kinds of other things of which they prided themselves, but now the nearness of God’s glory is what they live for and this is reflected in their deeds. People never hide that in which they pride themselves.1
2 Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God.
