Matt 28the LORD Jesus is currently ruling His Kingdom
His Kingdom is not of this world/age = John 18:36
"Jesus answered, “My kingdom is not of this world; if it were, My servants would fight to prevent My arrest by the Jews. But now My kingdom is not of this realm.”
the LORD Jesus Christ will Return and when HE does, He will rule the nations with a rod of iron.
18 Jesus came up and said to them, “All authority (all power of absolute rule) in heaven and on earth has been given to Me. 19 Go therefore and make disciples of all the nations [help the people to learn of Me, believe in Me, and obey My words], baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe everything that I have commanded you; and lo, I am with you always [remaining with you perpetually—regardless of circumstance, and on every occasion], even to the end of the age.”
Jn 19
- John 19:10
So Pilate said to Him, “You do not speak to me? Do You not know that I have authority to release You, and I have authority to crucify You?”
- John 19:11
Jesus answered, “You would have no authority over Me at all if it had not been given to you from above. For this reason the sin and guilt of the one who handed Me over to you is greater [than your own].”
Rev 1
4 John, to the seven churches that are in [the province of] Asia: Grace [be granted] to you and peace [inner calm and spiritual well-being], from Him Who is [existing forever] and Who was [continually existing in the past] and Who is to come, and from the seven Spirits that are before His throne, 5 and from Jesus Christ, the faithful and trustworthy Witness, the Firstborn of the dead, and the Ruler of the kings of the earth. To Him who [always] loves us and who [has once for all] freed us [or washed us] from our sins by His own blood (His sacrificial death)— 6 and formed us into a kingdom [as His subjects], priests to His God and Father—to Him be the glory and the power and the majesty and the dominion forever and ever. Amen. 7 Behold, He is coming with the clouds, and every eye will see Him, even those who pierced Him; and all the tribes (nations) of the earth will mourn over Him [realizing their sin and guilt, and anticipating the coming wrath]. So it is to be. Amen.
8 “I am the Alpha and the Omega [the Beginning and the End],” says the Lord God, “Who is [existing forever] and Who was [continually existing in the past] and Who is to come, the Almighty [the Omnipotent, the Ruler of all].”
Jesus never said he comes a second time to rule this earth. He comes to restore all things. Jesus said this heaven and earth will pass away as he comes to usher in the new.
