That “Jesus is Lord” is the foundation of at least two Pauline texts on “gospel” and the connection of Kingship to “gospel” is found in the “gospels” extensively, and OT Hebrew thought as well as Roman thought.
I think a Wright place to look is What Saint Paul Really Said.
Some lines of thought:
1] The gospel is referred to repeatedly as “the gospel of/about the kingdom” and therefor is good news about who is king.
put this together with the existing roman idea:
2] Roman Use: when a Caesar announced his accession to the throne, and his conquering of the enemies, and/or his birth into deity, this was called “euaggelion” (gospel) SEE THIS about Augustus:
The providence which has ordered the whole of our life, showing concern and zeal, has ordained the most perfect consummation for human life by giving to it Augustus, by filling him with virtue for doing the work of a benefactor among men, and by sending in him, as it were, a deliverer for us and those who come after us, to make war to cease, to create order everywhere. . . . ; the birthday of the god [Augustus] was the beginning for the world of the gospel that has come to men through him…

3] Gospel means announcing who is lord in the Roman mind. What about the Jewish mind?
Isaiah 52 (Septuagint says “gospel” where I have inserted it):
v. 7 How beautiful on the mountains
are the feet of those who bring good news [gospel],
who proclaim peace,
who bring good tidings,
who proclaim salvation,
who say to Zion,
“YOUR GOD REIGNS!”
in the midst of a passage about the subservience of the gentile kings to Israel, we find a passage highly suggestive of the Nativity:
v.6: A multitude of camels shall cover you,
the young camels of Midian and Ephah;
all those from Sheba shall come.
They SHALL BRING GOLD AND FRANKINCENSE,
and shall bring good news [gospel in LXX], the praises of the LORD.
The kings of Gentiles bowing before Israel is reminiscent of the SON of DAVID/KING OF ZION/SON OF GOD/MESSIAH mentioned in Psalm 2 (more on this later).
that is – The gentile kings bow before God’s true Lord – DAVID’S SON (Psalm 2)
4] Does Paul see it this way? (remember that Messiah/Christ already means “annointed as king”, and that “Son of God” is a Davidic Kingship title in Ps 2 and Ps 89, and so is therefore “Son of David”
1 Paul, a servant of CHRIST Jesus, called to be an apostle, set apart for the GOSPEL OF GOD, 2 which he promised beforehand through his prophets in the holy Scriptures, 3 concerning HIS SON, who was DESCENDED FROM DAVID according to the flesh 4 and was declared to be the SON OF GOD in power according to the Spirit of holiness by his resurrection from the dead, Jesus CHRIST our LORD, 5 through whom we have received grace and apostleship TO BRING ABOUT THE OBEDIENCE of faith for the sake of his name AMONG ALL THE NATIONS [Gentiles], 6 including you who are called to belong to Jesus CHRIST,
And again in much abreviated form in
2 Tim 2.8:
Remember Jesus CHRIST, raised from the dead, DESCENDED FROM DAVID. THIS IS MY GOSPEL…
The formula – 1) Resurrection, 2) Lordship (David’s Rightful King [Ps 89, or Ps 2]). Again:
9 …because, if you CONFESS WITH YOUR MOUTH THAT JESUS IS LORD, and believe in your heart THAT GOD RAISED HIM FROM THE DEAD, you will be saved. 10 For with the heart one believes and is justified, and with the mouth one CONFESSES and is saved.
This confession seems to be the same as the “confession” in Phil 2: “every tongue will confess that Jesus CHRIST is LORD to the Glory of God the Father.”
“Confess” there translates the OT use “to swear allegiance” from Is 45:22-23.
[[This is why we read that 1 Peter 4.17, Rom 10.16, and 2 Thes 1.8 talk about “obeying the gospel”]]
