The works of the Holy Spirit. The language spoken by Jesus here is speaking to the work done by John by the Holy Spirit. Rember John was filled with the Holy Spirit while in his mother's womb
The speaking of Elijah by Jesus is figuratively the person Elijah only did what they did because of the Holy Spirit or in the Old Testament the Spirit of the Lord.
This is incorrect. I understand why you are saying it, and it will take me a long time to explain why. But let me start here.
Man is not the body. Man is a Spirit Being, Programmed in the soul and immersed or baptised into their physical body. Elijah of tishbe is not the Most Holy Spirit of GOD, His Spirit being is himself. John the Baptist is the same. What John the Baptist's biological mother felt, that was called "The Holy Spirit" is actually the Spirit Being of John the Baptist.
You, and me, and all the children of the kingdom are Spirit Beings, programmed in the soul, and immersed into the physical body by the GOD. This we learned happens in the 6th - 7th month of pregnancy. The evidence is the fact that it was noted that John the Baptist bioloigical mother was 6th months into her pregnancy at that time.
Proof is that it is GOD who gives children. A child is born, a son is given. The physical body is what was formed in the womb, stitched by the seed that the Man sows into the woman that fertilizes an egg. The Spirit Being of the person is the real person. The children of the kingdom are all in the fathers Bosom before they are programmed in the soul and baptised or immersed into the physical body. And there is the total number of them; its not infinite. The mission of procreation will end.
All the children of the kingdom are holy spirits. GOD is the Most Holy Spirit. And tares are unholy spirits. A tare cannot become a wheat. A wheat cannot become a tare. What matters is where the Spirit Being is from. When GOD does not respect the comception, HE does not send a child of the kingdom into that womans womb. It is at that time, that the an unholy spirit is sent from the abyss and enters into that body. Lucfier is a tare cherub. His Spirit being comes from the Abyss. GOD allowed it because darkness needed to be defined, for light to also be defined. All the tares are cast into the lake of fire. A child of the kingdom can never be cast into the lake of fire.
In short, all the Spirit Beings of the children of the kingdom were birthed, or produced in the fathers Bosom according to their order. There is first of all Father Adam, who produced his model type, Mother Eve, and then produced three sons. The proof is that GOD took a from the body of Father Adam to couple the body of Mother Eve. These three sons are the three Elijah.
Then the three Elijah produced their model types, and produced 4 sons each. These make up the 12 Patriarchs of the 12 tribes of Israel.
Then the 12 Patriarchs each produced their model types, and produced 12 sons each. These are the 144.
Then the multiplication started as each man produced his model type, and produced 12 sons each. And this continued until the Man could no longer produce his model type. These are the ones called "eunuch's of the kingdom because they could not produce sons. It is these children that are candidates of the second resurrection because they do not have their model types.
This is the order of the Mankind race. The head of Man is Father Adam. The Elijah are the Prophets of the highest order. The 12 Patriarchs of the 12 tribes are the next in seniority, then the 144 are the next. And it goes down the line of production.
All the Spirit Beings of the children of the kingdom wait in the fathers Bosom for their time to be sent into this earth to pick up a physical body. Our physical body is needed because that is the body that will transfigure, be it in life alive, or resurrection. For no man can enter into heaven without the celestial, immortal body.
Elisha showed great ignorance when he said: Give me a double portion of your Spirit. And Elijah replied, Thou hast asked a hard thing: nevertheless, if thou see me when I am taken from thee, it shall be so unto thee; but if not, it shall not be so.
Elisha wasn't supposed to stay behind, Elisha was supposed to transfigure and go with him. But Elisha did not complete his race. Meaning, he did not overthrow his mortal body and put on the immortal celestial body in life. So he had to stay.
Thus, John the Baptist is one of the Elijah.
