Paul says:
Rom 15:19 Through mighty signs and wonders, by the power of the Spirit of God; so that from Jerusalem, and round about unto Illyricum, I have fully preached [SUP](G4137) [/SUP]the gospel of Christ.(Please NOTE: Not the gospel "about" Christ, but the gospel "of" Christ, of which that gospel of Christ was about the coming KINGDOM OF GOD/HEAVEN on Earth.)
"fully preached" = pleroo = G4137
πληρόω
plēroō
play-ro'-o
From G4134; to make replete, that is, (literally) to cram (a net), level up (a hollow), or (figuratively) to furnish (or imbue, diffuse, influence), satisfy, execute (an office), finish (a period or task), verify (or coincide with a prediction), etc.: - accomplish, X after, (be) complete, end, expire, fill (up), fulfil, (be, make) full (come), fully preach, perfect, supply.
Jesus says:
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. [SUP](G4137 = pleroo=FULLY PREACH)[/SUP]
Did Jesus come to fully preach that which was of the law and prophets?
Eze 37:12-23 Therefore prophesy and say unto them, Thus saith the Lord GOD; Behold, O my people, I will open your graves, and cause you to come up out of your graves, and bring you into the land of Israel. And ye shall know that I am the LORD, when I have opened your graves, O my people, and brought you up out of your graves, And shall put my spirit in you, and ye shall live, and I shall place you in your own land: then shall ye know that I the LORD have spoken it, and performed it, saith the LORD. The word of the LORD came again unto me, saying, Moreover, thou son of man, take thee one stick, and write upon it, For Judah, and for the children of Israel his companions: then take another stick, and write upon it, For Joseph, the stick of Ephraim, and for all the house of Israel his companions: And join them one to another into one stick; and they shall become one in thine hand. And when the children of thy people shall speak unto thee, saying, Wilt thou not shew us what thou meanest by these? Say unto them, Thus saith the Lord GOD; Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, even with the stick of Judah, and make them one stick, and they shall be one in mine hand. And the sticks whereon thou writest shall be in thine hand before their eyes. And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all: Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwellingplaces, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
Eph 2:13-17 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
And came and preached peace to you which were afar off, and to them that were nigh.
THE TWO KINGDOMS, SPLIT AND EACH TAKEN INTO CAPTIVITY FOR DISOBEYING THE COMMANDMENTS AND BREAKING THE COVENANT. THE HOUSE OF ISRAEL WAS DIVORCED FROM GOD (Jer 3:8 And I saw, when for all the causes whereby backsliding Israel committed adultery I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also.) AND THROUGH CHRIST'S DEATH, BURIAL AND RESURRECTION THEY (LOST SHEEP OF THE HOUSE OF ISRAEL) CAN BE FOUND AND REUNITED. THUS A NEW COVENANT IN THE MAKING!!
For over 1900 years, the gospel message of the Kingdom of God has not been preached by the church in large part. But now we are in the Last Days ...
Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
