It is not possible for John, the Baptist and John, the Apostle to be the same person, because they have two different sets of parents. John, the Baptist is the son of Zacharias and Elisabeth, and John, the Apostle is the son of Zebedee.
5 There was in the days of Herod, the king of Judaea, a certain priest named Zacharias, of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth.
11 And there appeared unto him an angel of the Lord standing on the right side of the altar of incense. KJV
21 And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them. KJV
When the Lord told me that John, the Baptist was John the Apostle, He was saying that they had the same spirit.
John, the Apostle, was John, the Baptist’s disciple before he was Jesus’ disciple, and he is also the subject of this study. The Apostle John was writing about himself in John, Chapter 4.
35 Again the next day after John stood, and two of his disciples; KJV
The first disciple is Andrew ….
40 One of the two which heard John speak, and followed him, was Andrew, Simon Peter's brother. KJV
….but the second disciple is not named. However, many Bible scholars believe that the second disciple was John, Jesus’ beloved Disciple, who became John, the Apostle.
John, the disciple, had a soul tie with John, the Baptist, his teacher, and he also had his teacher’s spirit, which was the spirit of Elias (Elijah).
17 And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord. KJV
Jesus also had the spirit of Elias (Elijah).
46 And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?
47 Some of them that stood there, when they heard that, said, This man calleth for Elias. KJV
The two, Jesus and John, had the same spirit from the womb.
41 And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: KJV
John, the disciple of John, the Baptist, also had a soul tie with his teacher, John, the Baptist.
It was intended from the beginning that the Spirit of Elias (Elijah) which was divided between Jesus and John at the time of its incarnation, would be joined in the earth through a soul tie between the two men. But the wisdom of God, knowing in advance that Herod would execute John, the Baptist, arranged for John, the disciple of John, the Baptist, to become Jesus’ disciple.
So, John, the disciple of John, the Baptist, who shared his teacher’s soul and the spirit of Elias through their Teacher-Disciple relationship, became the beloved disciple of Jesus.
I always had a problem believing that John physically leaned on Jesus’ breast at supper, and preached that that unusual phraseology must surely indicate a soul tie.
20 Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? KJV
I now understand that the Greek word translated, breast, means, chest, and the chest is the front surface of a physical body between the neck and the abdomen.
Jesus and John were joined by the spirit of Elias (Elijah) that resided in their respective neck (5th) energy centers.
Also, the same Scripture indicates that Jesus loved John. The Greek word translated, love, is, agape, which is called a moral love, because it is neither physical nor emotional.
Agape love, called the love of God, is the intimacy that arises out of sharing a common morality. Jesus and John were joined in their mind through their commitment to the morality of God, which means that they could not have had a homosexual relationship, as some might suggest.
And last, but not least, is the Greek word translated, supper. This word means, the chief meal, but I suggest to you that the spiritual meaning is appropriate here:
The glue of the special relationship that the two men, Jesus and John shared, which was founded upon the spirit of Elias (Elijah) and sanctified by their mental commitment to physical purity, was the Word of God and, in particular, the revelation knowledge of the age to come that Jesus brought to Israel.
