Reigning in life is “unto eternal life”—Romans 5:21. ...By giving grace to us, God manifests His righteousness (see Romans 1:17). Furthermore, the power of this grace operates in us and produces subjective righteousness, making us right with God, with others, and even with ourselves; and it not only subdues sin but also overcomes Satan and death in our being. Thus grace reigns through righteousness, resulting in eternal life. (Romans 5:21 Footnotes)
In eternity the whole New Jerusalem will express God. Furthermore, in eternity all the saved ones in the New Jerusalem will reign as kings with God (Rev. 22:5). This will be the dominion to represent God. Revelation 22:5 And night will be no more; and they have no need of the light of a lamp and of the light of the sun, for the Lord God will shine upon them; and they will reign forever and ever.
If a certain life does not grow, the law of that life cannot function. The law only operates as the life grows. The law of life does not primarily function in the negative sense of telling us what not to do. No, rather, while life grows the law of life functions in the positive sense of shaping us, that is, conforming us to the image of Christ. This is the function of the law of life. (Life-Study of Hebrews, ch.69; Romans 8:2, 29)
"For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord." Romans 8:38-39
Revelation 5:12. "It is matter of joy to all the world, to see that God deals with men in grace and mercy through the Redeemer. HE GOVERNS THE WORLD, NOT MERELY AS A CREATOR, BUT AS OUR SAVIOR... Christ has redeemed His people from the bondage of sin, guilt, and Satan." ~ Matthew Henry
When we with unveiled face are beholding and reflecting the glory of the Lord, He infuses us with the elements of what He is and what He has done. Thus we are being transformed metabolically to have His life shape by His life power with His life essence; that is, we are being transfigured, mainly by the renewing of our mind (Romans 12:2), into His image. Being transformed indicates that we are in the process of transformation. (2 Corinthians 3:18 Footnote 7)
God created a corporate man not only to express Him but also to represent Him by having dominion over all things. God’s intention in giving man dominion is to subdue God’s enemy, Satan, who rebelled against God—Genesis 1:26, 28. Genesis 1:28 And God blessed them; and God said to them, Be fruitful and multiply, and fill the earth and subdue it, and have dominion…
