Matthew 24:14 New International Version (NIV)
14 And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come.
Only one teaching will lead to salvation and the other one will lead to death forever
Both teachings will be from verses in NWT and mainstream translation of Christendom to compare both,before starting the reason both translations is the translators in many cases slanted the text to support the believe of that time,for example :
1 Tim 3-16 KJV
And without controversy
great is the mystery of godliness: God was manifest in the flesh,
justified in the Spirit, seen of angels, preached unto the Gentiles,
believed on in the world, received up into glory.
It was slanted to promote the Trinity saying God came to earth instead of the Son
Several other translation recognized this was in error of translation and corrected the text
ESV
Great indeed, we confess, is the mystery of godliness:
sHe5 was manifested in the flesh,the[ 5 ]there says Greek Who; some manuscripts God;
Beyond all question, the mystery from which true godliness springs is great: He appeared in the flesh,
New Living Translation
Without question, this is the great mystery of our faith: Christ was revealed in a human body
So the text was Christ came to earth not God,the word God was not in the original Greek text
KJV is widely used in Christendom
Another error in translation
John 8-7 KJV
This verse was added by the scribe ,not originally in the Greek text,Jesus never said these words
These are many more errors or misleading verses,one more passage to get the wrong conclusion;
King James 2000 Bible
Jesus said unto her, Touch me not; for I am not yet ascended to my Father:
He couldnt have told Mary this after his resurrection because later that day he told Thomas to touch me stick your hands in me,several others corrected the text;
Holman Christian Standard Bible
"Don't cling to Me,
NWT Jehovah's Witness
"Don't cling to Me
Christian Standard Bible
"Don't cling to me,
New American Standard Bible
Jesus said to her, "Stop clinging to Me
So for these reasons I will refer to several translations to get the complete understanding as to what was said and how it was said,there are many many more verses that either mislead or slant the text to the translators personal belief
Ill google what is the Rapture?

https://activechristianity.org/what-does-the-bible-say-about-the-rapture
For the Lord Himself will descend from
heaven with a shout, with the voice of an archangel, and with the
trumpet of God. And the dead in Christ will rise first. Then we who are
alive and remain shall be caught up together with them in the clouds to
meet the Lord in the air. And thus we shall always be with the Lord.
Therefore comfort one another with these words.” 1 Thessalonians 4:16-18.
Thats the belief of the Churches of Christendom This is suppose to happen when the end comes those saved will be wisked away to Heaven to forever be with Jesus.
JWs teaching
New World begins here on eart for 1,000 years
The Churches have a problem with this verse
Rev 20-2
New International Version
He seized the dragon, that ancient serpent, who is the devil, or Satan, and bound him for a thousand years.
This is what Witnesses believe that the earth will be a paradise and Satan will be released to mislead earth inhabitants all over again
Rev 20 3
And he cast him into the Abyss, and shut and sealed it
over him, so that he should not deceive the nations any longer, until
the thousand years were completed. After these things it is necessary
for him to be released for a little time.
The problem is since all the saved were taken to heaven a 1000 earlier where these people come from who Satan misleads after being released,certainly not those who are in heave would come back to the earth after their reward to be tempted by the Devil and a chance to be destroyed,makes no sense
JW teaching makes more sense that during the 1,000 many ones will be born and never was tempted loyalty and those ones who survived the end will grow to perfection and can now say they are under Adamic sin he brought on all mankind ,thats why Satan was not destroyed 1,000 earlier,man always told God why do I have to suffer for what one man did if I was there I may have been obedient ,so they will get that chance standing on their own merit
Ive asked preachers that question as to where the people come form to be tempted by the Devil and some say those saved a 1,000 earlier will come back to the earth with Christ who will set up his Kingdom here on earth,so what was the purpose of the Devil not being destroyed 1,000 earlier and will those who were in heaven now back on earth be the ones tempted,they dont know but just say Revelation is a book of symbols
There you have it both beliefs ,which one harmonizes with the scriptures
