That is good except there will be a time when He ceases His role as Son and resume His role as the Eternal Spirit of God.
After Satan is cast into the lake of fire and all sin is judged at the last judgment (Revelation 20), there will be no further need for the Son to exercise the throne of power. Jesus Christ will cease acting in His Sonship role and will be God forever.
Does this mean that God will cease using the resurrected and glorified body of Christ? We believe that Jesus will continue to use His glorified body throughout eternity. This is indicated by Revelation 22:3-4, which describes a visible God even after the last judgment and after the creation of the new heaven and earth: “And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: and they shall see his face; and his name shall be in their foreheads.”
Even the Son will be placed under subjection so that God may be all in all. It is in this sense that the Sonship will end.
Nowhere in Scripture are we told or is it even suggested that the Father/Son relationship comes to an end.
In Hebrews 1:8 God the Father calls the Son God, and tells Him his throne is forever.
"But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom."
Christ will rule the world forever in the Kingdom the Father has given Him.
