JWs teach that the Father created Jesus who was the angel Michael and Jesus is "mighty god" (NWT Is 9:6) and "a god" (NWT John 1:1).
However, read this verse.
Isaiah 43:10 (New International Version)
10 "You are my witnesses," declares the LORD,
"and my servant whom I have chosen,
so that you may know and believe me
and understand that I am he.
Before me no god was formed,
nor will there be one after me.
There is no way the WT teaching can be true in light of this or even the Mormon teaching that we will all be Gods.
The only explanation is that Jesus and the Father are one John 10:30 and that Jesus is God John 20:28, Philippians 2:5-7, Matthew 1:23
Want more proof?
Isaiah 44:8 (New International Version)
8 Do not tremble, do not be afraid.
Did I not proclaim this and foretell it long ago?
You are my witnesses. Is there any God besides me?
No, there is no other Rock; I know not one."
That Rock is Jesus, see here
1 Corinthians 10:3-4 (New International Version)
3 They all ate the same spiritual food 4 and drank the same spiritual drink; for they drank from the spiritual rock that accompanied them, and that rock was Christ.
And here
1 Peter 2:4-8 (New International Version)
The Living Stone and a Chosen People
4 As you come to him, the living Stone—rejected by men but chosen by God and precious to him— 5 you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. 6 For in Scripture it says:"See, I lay a stone in Zion,
a chosen and precious cornerstone,
and the one who trusts in him
will never be put to shame." [ a ] 7 Now to you who believe, this stone is precious. But to those who do not believe,
"The stone the builders rejected
has become the capstone, [ b ] " [ c ] 8 and,
"A stone that causes men to stumble
and a rock that makes them fall." Don't trip up on who Jesus is.
All the best,
Stephen
