1 John 5:7-8
1Jn 5:7 For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
The NIV and NWT follow the same spirit:
The Logical evidence:
1Jn 5:8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
Divine inspiration without Divine preservation would be a Divine waste of time. This particular phrase whether in text or margin, quotations for varied persons in history, thus has been around a long time, and even with the Textus Receptus [TR], and moreso, in the King James Bible [the preserved word of God in English] for over 400 years. It is obviously being preserved by that which is greater than the human capability or mind.
The phrase is also unique to John, in that the text does not refer to the specific terms of the Father, the Son and the Holy Spirit, but rather to the Father, the Word and the Holy Ghost. The phrase "the word", in reference to the person of the Son, is unique to John's mind, among the gospel and epistle writers.
Just standing back and looking at it objectively, the phrase that is in dispute by critics [see wikipedia, etc], is actually quite large to have been purposefully inserted at some point in early history after the completion of the original text, but it would be far easier to drop it in transmission, transcribing.
Some may argue that the phrase is not in the majority of Koine Greek witnesses, and is therefore not to be retained. This is a logical fallacy. While it is true that it is not in the majority of Greek 'witnesses' [most of which are late mss, etc], that does not preclude its having been originally therein, nor of it's validity as standing in the texts of the other languages of the world, such as Latin, etc.
God never stated that He had to preserve His living word in any singular language, even dead [Koine Greek, Latin, etc] languages at that.
God never stated that He would preserve His word in just the 'early' works and fragments, or in just the 'late' works and fragments which are found in the dusty forgotten places of the world. He may use any combination thereof He chooses.
God never stated that He would preserve His word in the majority of texts. God is able to save by many, few or even just one. For instance, see the battles of Gideon and the 300 [Judges 6 KJB], or Jonathan and his armour bearer:
1 Samuel 14:6 KJB - And Jonathan said to the young man that bare his armour, Come, and let us go over unto the garrison of these uncircumcised: it may be that the LORD will work for us: for there is no restraint to the LORD to save by many or by few.
God is able to re-inspire a text that has been destroyed through various means [in fact, this is how DNA itself, which is a written language, works, when mutations, errors occur within itself. It has a self correcting mechanism.], for instance see the examples of Moses and Jeremiah:
Jeremiah 36:20 KJB - And they went in to the king into the court, but they laid up the roll in the chamber of Elishama the scribe, and told all the words in the ears of the king.
Jeremiah 36:21 KJB - So the king sent Jehudi to fetch the roll: and he took it out of Elishama the scribe's chamber. And Jehudi read it in the ears of the king, and in the ears of all the princes which stood beside the king.
Jeremiah 36:22 KJB -Now the king sat in the winterhouse in the ninth month: and [there was a fire] on the hearth burning before him.
Jeremiah 36:23 KJB -And it came to pass, [that] when Jehudi had read three or four leaves, he cut it with the penknife, and cast [it] into the fire that [was] on the hearth, until all the roll was consumed in the fire that [was] on the hearth.
Jeremiah 36:24 KJB - Yet they were not afraid, nor rent their garments, [neither] the king, nor any of his servants that heard all these words.
Jeremiah 36:25 KJB -Nevertheless Elnathan and Delaiah and Gemariah had made intercession to the king that he would not burn the roll: but he would not hear them.
Jeremiah 36:26 KJB -Then the word of the LORD came to Jeremiah, after that the king had burned the roll, and the words which Baruch wrote at the mouth of Jeremiah, saying,
Jeremiah 36:27 KJB -Take thee again another roll, and write in it all the former words that were in the first roll, which Jehoiakim the king of Judah hath burned.
Jeremiah 36:28 KJB - And thou shalt say to Jehoiakim king of Judah, Thus saith the LORD; Thou hast burned this roll, saying, Why hast thou written therein, saying, The king of Babylon shall certainly come and destroy this land, and shall cause to cease from thence man and beast?
Notice Matthew 1:11 KJB:
Matthew 1:11 KJB - And Josias begat Jechonias and his brethren, about the time they were carried away to Babylon:
Notice who is suddenly 'missing'?
... (for it was Jehoiakim that begat Jechonias, and Josias the father of Jehoiakim (2 Kings 23:34; Jeremiah 1:3, 22:18, 25:1, 26:1, 27:1, 35:1, 36:1,9, 45:1, 46:2) and was Jechonias' grandfather (1 Chronicles 3:16; Jeremiah 22:24, 24:1, 27:20, 28:4, 37:1; "Coniah" = "Jeconiah/s")), but why?
It was for what he did to the word of God; which was cutting it up into pieces and having it burned.
On another note, some 'skeptics' , or even so-called Bible scholars [like the 'lawyers, scribes, etc of Jesus' day], try to point out in scripture, like this location, and say, “See, your Bible cannot be trusted, as it has gaps in the Genealogies, and therefore who knows how many persons are missing, etc, etc.” Yet, the only reason we know that there are so-called “gaps” in certain places like Matthew or elsewhere in the first place, is because those so-called “gaps” are filled in elsewhere, which means, there are no actual gaps in scripture [KJB].
Also, this particular example is good, because of what else it shows. Namely, that even though Jeremiah wrote [through Baruch; Jeremiah 36:1-4 KJB] the original note/letter and sent it to the King, from God, the King cut up and burned the original copy
. Therefore, that “original manuscript” is forever lost [except God bring it back through miracle].
This goes to show that those who claim to only believe the “original manuscripts” do not know what they are talking about.
The “original manuscripts” are long gone, destroyed, burned, faded, erased, or re-used [called a 'palimpsest', scrape over a lambskin, etc and rewrite on top], buried at sea and eaten, and so on.
God does not care so much about the “originals” as He does about simply “preserving” His word [see Psalms 12:6-7 KJB], generally through memory, copying, etc.
Well, since the King cut up and burned [Jeremiah 36:23 KJB] the “original” manuscript copy of the letter by Jeremiah/Baurch, how then do we have a copy of it in scripture to read [Jeremiah 36 KJB]? Did you take notice all of the times that “scribes” are near at hand, making copies of what is said, or written? What was more important, the “original” or preserving what was said by God?
Obviously preserving the words, not the “original” manuscript.
Yet, this is not all, for we even see that God had Jeremiah/Baruch, write an “original” manuscript number 2, to repeat what was in the first “original” with even more words, see Jeremiah 36:28,32 KJB. Therefore, we see, that if a piece of God's word be maliciously destroyed, God, through one means or another, preserves it. In this instance, Jeremiah and Baruch were to write such again, and add more to it.
Thus we now have “original” manuscript number 2.
Yet this “original” manuscript is taken and tied to a stone and cast into the Euphrates river [Jeremiah 51:63 KJB], thus eliminating “original” manuscript number 2, by decree of God, through an angel.
How then do we have those words in Jeremiah since the “original” manuscript 2 was purposefully destroyed at God's own command? Well, someone obviously made a copy of those words, either Jeremiah/Baruch, or a “scribe” in either the Temple or King's court, etc and thus we then have “original” manuscript number 3.
Yet, to be sure, “original” manuscript number 3 is more than likely, as the other two, long since been disintegrated. It is not the “originals” that are important, but rather it is the preservation [by God] of those words which were given by God [Acts 1:16; 2 Timothy 3:16; 2 Peter 1:21 KJB].
Consider also the original Tables of Stone written upon by the finger of God, were broken by Moses [Exodus 32:19; Deuteronomy 9:17 KJB].
Was the medium of the material important as much as the words, or were the words to be preserved instead on a new [though similar] medium [Exodus 34:1; Deuteronomy 10:2 KJB]?
God's words are still available today in the preserved word of God, in English, the King James Bible, and may be found in Exodus 20:1-17 KJB. No old fragment of an "original" is needed. God's word is "quick" ['living'; Hebrews 4:12 KJB], not dead.
