I will worship toward thy holy temple,
and praise thy name
for thou hast magnified thy word above all thy name.
“God” or “Lord God” can refer to the Godhead, God the Father, or Jesus Christ. I think it usually refers to the Godhead - the trinity of Father, Son, and Holy Ghost.
“Lord” can refer to God the Father or Jesus Christ. It usually refers to Jesus Christ as your personal lord.
"LORD" is “Jehovah” as God or Lord God, our triune ruler of all things.
“Holy Spirit”, “Spirit of God”, and “Holy Ghost” refer to the third part of the Godhead, most often called the Holy Spirit. “Holy Spirit” is used in a corporate sense meaning its spirit generally dealing with all people. “Holy Ghost” is used in an individual sense, meaning the spirit dealing with you alone. Either way, He is the same.
The “Word of God” is always Jesus Christ.
Now look at these two verses:
I Corinthians 15:28
And when all things shall be subdued unto him,
then shall the Son also himself be subject unto him that put all things under him,
that God may be all in all.
For in him dwelleth
all the fulness of the Godhead bodily.
These two verses indicate that once the kingdom is established, following the millennium, that God will be one person. His body will encase his soul and spirit, and He will be known to us as Lord Jesus Christ, especially if heaven #3 is part of the new heavens.
Righteousness has been established and there is no sin or rebellion from the subjects of God.
Jesus Christ, the Word of God, can be all in all in one body encompassing the fullness of the Father, Son, and Holy Spirit. He will then rule and reign over all things forever and forever from “the throne of God and of the Lamb” in the new Jerusalem through his righteous and perfect Israelites and bride.
