Amazing Internal Evidence for 1 John 5:7's Authenicity directly from Scripture. Take notes on, write down, and save this post, as the evidence of Scripture is very important when defending 1 John 5:7 and showing that 1 John 5:7 was indeed written by the Apostle John. Internal evidence, when refering to verses in Bible/the Scriptures, is the words in Scripture that show both a verse's importance and a verse needs to stay/be kept in the Bible, not removed from Scripture.
👉First, the word phrase of "the Word" in 1 John 5:7 is unique to and matches the Apostle John's consistent use of the phrase "the Word" to call Jesus as God. Compare 1 John 1:1 and 1 John 5:7 with John 1:1-3, 14, all of which show that Jesus is God the Word/God the Son, that Jesus created all things, that Jesus came to earth in the flesh, and that Jesus both is with God the Father in heaven and was with the Father in heaven even before Jesus created all things:
John 1:1-3, 14 KJB
[1] In the beginning was the Word, and the Word was with God, and the Word was God. [2] The same was in the beginning with God. [3] All things were made by him; and without him was not any thing made that was made. ...[14] And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
1 John 1:1-3 KJB
[1] That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; [2] (for the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;)
[3] that which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
1 John 5:7
[7] For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
👉When the words of "in heaven, the Father, the Word, and the Holy Ghost: and these three are one." is omitted (and is so removed by Gnostics, Arians, hereticks, cults and false religions, lying modernist scholars of the late 1800s, and the 1900s & 2000s, and all modern versions and their proponents/promoters [which call most of 1 John 5:7 as Comma Johanneum]) out of 1 John 5:7, then we miss both the fact and the connection between Revelation 4:2 and 1 John 5:7: 1 John 5:7 identifies who "one sat on the throne" (of Revelation 4:2) in heaven is: the Father, the Word, and the Holy Ghost of 1 John 5:7 bear record and sit on God's throne in heaven as per 1 John 5:7 and Revelation 4:2, when 1 John 5:7, including "Comma Johanneum", is kept and preserved in the words of 1 John chapter 5:
Revelation 4:2 KJB
[2] And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne.
👉Without 1 John 5:7, the three witnesses in earth of the spirit, the water, and the blood of 1 John 5:8 do not have a "these three agree in one" of 1 John 5:8 to be the one that they agree in.
1 John 5:7-8 KJB
[7] For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. [8] And there are three that bear witness in earth, the spirit, and the water, and the blood: and these three agree in one.
Notice how the earthly witnesses (which are "the spirit, and the water, and the blood:") agree "in one". This reference of "in one" points back to 1 John 5:7's reference of "the Father, the Word, and the Holy Ghost: and these three are one.", because the "three" in "these three are one" are the Father, the Word, and the Holy Ghost and 1 John 5:8's words "agree in one" refers back to the "these three are one" since the earthly witnesses ("the spirit, and the water, and the blood") agree in one, which is the heavenly witnesses ("the Father, the Word, and the Holy Ghost") of 1 John 5:7.
Thus, without 1 John 5:7 / the "Comma Johanneum", the earthly witnesses of 1 John 5:8 have no "one" to "agree in".
