Why are folks so adamant that Jesus is God. Psalm 83:18 says God is Jehovah and John 17:3 says it means our life to know Jehovah and Jesus.?

The Bible is adamant that the One who became Jesus Christ was God. Just read John 1:1-14.

John 17:3 does not say that knowledge of Jehovah and Jesus means our everlasting life, for Satan and the demons have far more knowledge about the Father and the Son that we presently have. It says that KNOWING the Father and the Son is life everlasting. That is not a head trip - that requires a heart transplant, carried out by the Holy Spirit.

1) Why are folks so adamant that Jesus is God.

Because those people believe what the Bible teaches. For example:

2) Psalm 83:18 says God is Jehovah

Not logically relevant to the topic under discussion.

3) and John 17:3 says it means our life to know Jehovah and Jesus.?

No, it doesn't.

Conclusion: when you...misrepresent a Bible passage in order to support your point, it's clear that your point is not supported by the Bible.

Because they are blinded by Satan.

Because Jehovah lets them remain foolish in their belief.

Because like their father Satan, they want to decide for themselves what is right and what is wrong.

Trinitarians need to pray to the God and Father of our Lord Jesus Christ for wisdom and accurate knowledge of him, the only true God, and the one whom he sent, Jesus. (Eph 1:1, 17; John 17:3; Rev 3:2)

..................

Edit: So at least 10 people have refused to pray to the God and Father of our Lord Jesus. So sad, so sad.

Jesus, before he was born, was known as Jehovah. As Jehovah he created the earth, and without him was not anything created that was created. (John 1) It is Jehovah, and Jehovah alone who forgives sin. When Jesus told people that their sins were forgiven, it was in his role as Jehovah. It is Jehovah that walks on the waves and calms the storm. It is Jehovah who heals the blind. The brazen serpent, which Moses created and put in the camp of the Israelites represented Jehovah, the savior of the Israelites, and the son of God.

That is why Jesus is never called the Son of Jehovah, and why Jesus never prays to Jehovah.

Mostly because Jesus said he was God. There are others that said so as well, including Saint Thomas who did it to Jesus' face.

Because it's what the Bible teaches. It's what the apostles taught. It's what the very first Christians like "Ignatius" believed. It's what Jesus' church (whom he said the gates of hell would never prevail against) has always taught - and STILL teaches in 2019.

You say Jesus is not God - but the very same 'Father' from John 17:3 that Jesus was referring to says the opposite. Shall we believe your word, or his?

"But about the Son He says: “Your throne, O God, endures forever and ever, and justice is the scepter of Your kingdom." Hebrews 1:8

Jesus is explicitly called God in many places in the New Testament. One famous ex in John 20:28: where Thomas said to Jesus (direct address): "the Lord of me and the God of me"

A case can be made even from your organizations translation; which the majority of the Christian world don't accept because the text was tampered with to conform to Jehovah Witness theology. "Jehovah" is NOWHERE in the Greek manuscripts, and you had NO right to add it in there where it wasn't in the first place.

And just in case that wasn't good enough the NT authors also frequently used OT passages that referred to Jehovah in reference to the Son. Some examples: Isaiah 6:1 with John 12:37-41. Psalm 102:25-27 with Hebrews 1:10. 1 Peter 3:14-15 with Isa. 45:23.

Jehovah is not just the Father alone. The New Testament revelation is that Jesus' shares in the same nature and glory and name. Along with the Holy Spirit. All three of them together exist as the One God Jehovah.

An exalted archangel, a mere exalted man, any being outside of Jehovah CANNOT save you from your sins. Jesus has to be God. Just by the fact that he demanded us to love him more than anything in our life demonstrates that. Like C.S. Lewis he's either a "Lunatic, Liar, or Lord."

To put it blunt -- the Watchtower has it wrong. That organization constantly lies and misrepresents what we believe as Christians.

I'll be willing to chat with you if you'd like... but most of the time all I ever see on here from jw users are mindless talking points from Jw.org along with questions about the Trinity always addressed to fellow jw's or best answers always given to fellow jw's no matter the question is. Sincerity about the truth is rare these days.

We understand that God gave Himself for our justification.

That God in Christ provided for us what we can not achieve ourselves ... God paid the price of our adoption.

How many God's are there?” The answer is obvious that there is only one God. 

If he is one God, then could he be three gods, God the Father, God the Son and God the Holy Ghost, as the Trinitarians teach? 

No, Jehovah could not be three gods, for the Bible plainly says he is one God. How can there be (3) three when the Almighty God says there is only (1) one.  

Isa 45:5,6  

I am Jehovah, and there is no one else.  

There is no God except me.  

Now, you have caused a basic Scriptural truth and to understand that Jehovah is but one God. You have also exposed a basic false doctrine the doctrine of the Trinity.

(Sigh) More JW trolls. To first say the Bible isn't correct you have to establish which version you're using. The flawed NWT version JW's created to jibe with their warped beliefs, or the real Bible? Let's not do the cut & paste thing where I literally show you EVERY Biblical reference to the deity of Christ.

Jesus is not god. Jehovah Witnesses are correct on this teaching. Why would god sacrifice himself? Jesus constantly mentioned "his father".
