"Who, being in very nature God, did not consider equality with God something to be used to his own advantage;" NIV
"Who, being in the form of God, thought it not robbery to be equal with God:" KJV
"Who, being in the form of God, thought it not robbery to be equal with God:" KJV
God is a Spirit: and they that worship him must worship him in spirit and in truth.
Spirit has no form as have natural things.
Therefore, the form of God referred to in the verse above is spirit.
"Thought it not" means that Jesus Christ never thought it, not once, not ever.
What did Jesus never think?
Jesus never thought "it robbery to be equal with God."
That is to say, that Jesus didn't think like Satan, and his rebel angels thought. They thought they could steal the authority of God and by taking his throne.
Jesus never thought he was equal with God, his Father.
But some of you think you can authorize yourselves as equal to the task of editing God's written word. Of course in that pursuit the same pretense God's written word doesn't exist on earth anymore.
The niv is stating that Jesus was equal to God, his Father, which can't be.
When the niv states that Jesus "did not consider equality with God something to be used" it is claiming that Jesus did consider himself his Father's equal but, didn't think his equality with God was something to use to his own advantage.
After this the niv gets worse, in that it claims that Jesus became nothing at all, which is not only impossible, but absurdly so, if thought true, as some apparently think.
And if you think Jesus Christ became nothing, then you agree with the spirit of antichrist, that spirit that denies the Jesus Christ came in the flesh.
Then the niv claims that Jesus didn't appear in the form of a servant, but took on the nature of a servant, as thought Jesus Christ didn't already serve God in heaven as the Word.
Whereas the the Holy Bible informs you that Jesus' took on the form of a servant, meaning that he appeared among his brethren as a man servant, as one that washes his brethren feet for an example.
The niv is rotten to its core and you geniuses can't read English, much less, translate anything.
What matters is not how well you claim you can translate, which you absolutely can't honestly do. But rather, can you tell the truth about Jesus Christ, confess your lies about him, and repent?
