1-Don’t bother listening to their rehearsed speech. Go on the offensive.
2-Ask them if Jesus is God, or was Jesus just a god. Their answer: Jesus is just a god, created by Jehovah. Only Jehovah is God. Ask them what is the Holy Spirit. Their answer: There is no Holy Spirit. That was just the power and force of God.
3-Borrow their New World Translation (their mistranslated/corrupted version of the bible) from them. You can read it online here.
New World Translation (2013 Revision) | Published by Jehovah’s Witnesses
4-Go to Revelation 1:8 and read: 8 “I am the Alʹpha and the O·meʹga,”
*q says Jehovah
* God, “the One who is and who was and who is coming, the Almighty.”
r
5-Ask them “Who is Alpha and Omega?” Ther answer: Jehowah
6-Go to Revelation 1:17-18 and read: 17 When I saw him, I fell as dead at his feet.And he laid his right hand on me and said: “Do not be afraid. I am the First
k and the Last,
l 18 and the living one,
m and I became dead,
n but look! I am living forever and ever,
o and I have the keys of death and of the Grave.
*p
7-Look them dead in the eyes and ask them “Who is the First and the Last? Who have the keys of death and of the grave” Their answer: Jehovah. Then ask them “When then did Jehovah die?” They will try to dodge this question by this point. But keep pressing them “When did Jehovah die, and then become alive again?” and don’t get distracted. Eventually they will try to say that “First and Last is only Jesus. Alpha and Omega is Jehovah”.
Also read Revelation 2:8 :
8 “And to the angel of the congregation in Smyrʹna write: These are the things that he says, ‘the First and the Last,’
+ who became dead and came to life again:
+
8-Go to Revelation 22:12–14 and read: 12 “‘Look! I am coming quickly, and the reward I give is with me, to repay each one according to his work.
o 13 I am the Alʹpha and the O·meʹga,
*p the first and the last, the beginning and the end. 14 Happy are those who wash their robes,
q so that they may have authority to go to the trees of life
r and that they may gain entrance into the city through its gates.
s
9-Ask them “Who is Alpha and Omega, first and last, beginning and end?” Their answer: Jehovah. Then ask them “But you just said that First and Last is only Jesus. Alpha and Omega is Jehovah.” Once again they will try to avoid this question. Keep pressing them about “When did Jehovah die, and then become alive again?”
10-Stay in Revelation 22 keep on reading to the end, verses 15–21: 15 Outside are the dogs
* and those who practice spiritism and those who are sexually immoral
* and the murderers and the idolaters and everyone who loves and practices lying.’
t 16 “‘I, Jesus, sent my angel to bear witness to you about these things for the congregations. I am the root and the offspring of David
u and the bright morning star.’”
v 17 And the spirit and the bride
w keep on saying, “Come!” and let anyone hearing say, “Come!” and let anyone thirsting come;
x let anyone who wishes take life’s water free.
y 18 “I am bearing witness to everyone who hears the words of the prophecy of this scroll: If anyone makes an addition to these things,
z God will add to him the plagues that are written in this scroll;
a 19 and if anyone takes anything away from the words of the scroll of this prophecy, God will take his portion away from the trees of life
b and out of the holy city,
c things that are written about in this scroll. 20 “The one who bears witness of these things says, ‘Yes, I am coming quickly.’”
d“Amen! Come, Lord Jesus.” 21 May the undeserved kindness of the Lord Jesus be with the holy ones.
11-Ask them about verse 13 “I am Alpha and Omega” and verse 16 “I, Jesus, sent an angel to bear witness to you”. Who sent this message to John, delivered by an angel? Jehovah or Jesus sent it? Then look at verses 12 and 20 and ask them “Who is coming quickly? Jehovah or Lord Jesus?” Then go to verse 17 and ask them “If the Holy Spirit is just the power of God and not an entity, how can it speak? And how can it be with the bride (believers)?” They will keep on dodging and avoiding your questions.
After they dodge around enough go to Revelation 22 verse 18. Ask them if they are guilty of adding and taking away any words on the prophecies of this scroll. Ask if they fear God’s plagues and losing the tree of life.
12-You can ask them to leave at this point. You’ve done your part and hopefully God will be merciful to these Jehovah’s Witness.
Conclusion (all from NWT):
A:Jehovah God calls himself
Alpha and Omega,
Beginning and the End. (Revelation 1:8)
B:Jesus calls himself the
First and the Last,
one who died but is living forever more. (Revelation 1:17–18)
C: Jesus calls himself the the
First and the Last, who became dead and came to life again. (Revelation 2:8)
D:Jesus calls himself
Alpha and Omega, First and Last, Beginning and the End. (Revelation 22:13)
So:
Jesus is Jehovah God.
Extra notes (These require reading Greek from the Interlinear bible):
Greek, Hebrew, Transliterated, English, Strong's
13-Go to NWT Revelation 22:8-9. Read:
8 Well I, John, was the one hearing and seeing these things. When I heard and saw them, I fell down to worship at the feet of the angel who had been showing me these things.
9 But he tells me: “Be careful! Do not do that! I am only a fellow slave of you and of your brothers the prophets and of those observing the words of this scroll. Worship God.”
n
14- Then go to NWT John 20:28–29. Read:
28 In answer Thomas said to him: “My Lord and my God!”
y 29 Jesus said to him: “Because you have seen me, have you believed? Happy are those who have not seen and yet believe.”
z
15- Ask the JW why Jesus didn’t rebuke Thomas when Thomas called Jesus capital God, as in Jehovah God, when the angel did. Their answer: The God here means “a god”, not Jehovah God. Tell them that they cannot claim that, because their own NWT used capital G. If they cannot even trust what their own NWT wrote, they got nothing to stand on.
Or they will say “Thomas say to Jesus my Lord, and then look to heaven and say my God”. No worries. Go to the interlinear bible and read: “The Lord of me
and the God of me!” Ask them why is the word “and” in the Interlinear Greek. And if “and” is there, how can JW claim that these two things were said separately.
16- Read John 1:1 in NWT: 1 In the beginning was the Word,
a and the Word was with God,
b and the Word was a god.
c
17-Ask them why it says “And the Word was a God” Their Answer: No article, so small g in Greek.
Then read John 1:6, 12 and 13. 6 There came a man who was sent as a representative of God; his name was John.
h ……. 12 However, to all who did receive him, he gave authority to become God’s children,
p because they were exercising faith in his name.
q 13 And they were born, not from blood or from a fleshly will or from man’s will, but from God.
r
Also read John 13:3: 3 So Jesus, knowing that the Father had given all things into his hands and that he came from God and was going to God,
f
18-Ask them why in verses 6, 12, 13 and John 13:3 they are translated as “God”, but in John 1:1 it is “a god”, when none of them have an article before the word “God”. Show them in the interlinear Greek. Once again they will dodge the question. Point here is that JW is inconsistent with their own translation. The JW’s NWT don’t even follow their own “No article, so small g in Greek” rule throughout.
