"Here again is brought to view the personality of the Father and the Son, showing the unity that exists between them. 8T 269.1"
"I and my Father are one."
The EGW passage directly addresses the unity between the Father and the Son, which is the central theme of John 10:30. The EGW passage amplifies the meaning of the verse.
"This unity is expressed also in the seventeenth chapter of John, in the prayer of Christ for His disciples: 8T 269.2 “Neither pray I for these alone, but for them also which shall believe on Me through their word; that they all may be one; as Thou, Father, art in Me, and I in Thee, that they also may be one in Us: that the world may believe that Thou hast sent Me. And the glory which Thou gavest Me I have given them; that they may be one, even as We are one: I in them, and Thou in Me, that they may be made perfect in one; and that the world may know that Thou hast sent Me, and hast loved them, as Thou hast loved Me.” John 17:20-23 . 8T 269.3"
"Neither pray I for these alone, but for them also which shall believe on me through their word; That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me."
Ellen White directly references John 17:20-23 in this passage.
"Wonderful statement! The unity that exists between Christ and His disciples does not destroy the personality of either. They are one in purpose, in mind, in character, but not in person. It is thus that God and Christ are one. 8T 269.4"
"And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are."
The EGW passage directly explains the type of unity that exists between Christ and his followers, drawing a parallel to the unity between God and Christ, which is the central theme of John 17:11.
"“Thus speaketh Jehovah of hosts, saying, Behold, the man whose name is the Branch: And He shall grow up out of His place; And He shall build the temple of Jehovah;... And He shall bear the glory, And shall sit and rule upon His throne; And He shall be a priest upon His throne; And the counsel of peace shall be between Them both.” Zechariah 6:12, 13 , A. R. V. 8T 269.6"
"Even he shall build the temple of the Lord; and he shall bear the glory, and shall sit and rule upon his throne; and he shall be a priest upon his throne: and the counsel of peace shall be between them both."
The EGW passage directly quotes Zechariah 6:12, 13.
