Hi Slim,
Re: Revelation 3:12 Adam Clarke writes:
A pillar in the temple - There is probably all allusion here to the two pillars in the temple of Jerusalem, called Jachin and Boaz, stability and strength. The Church is the temple; Christ is the foundation on which it is built; and his ministers are the Pillars by which, under him, it is adorned and supported. St. Paul has the same allusions, Gal_2:9.
I will write upon him the name of my God - That is, I will make him a priest unto myself. The priest had written on his forehead קודש ליהוה kodesh laihovah, “Holiness to the Lord.”
And the name of the city of my God - As the high priest had on his breastplate the names of the twelve tribes engraved, and these constituted the city or Church of God; Christ here promises that in place of them the twelve apostles, representing the Christian Church, shall be written, which is called the New Jerusalem, and which God has adopted in place of the twelve Jewish tribes.
My new name - The Savior of All; the light that lightens the Gentiles; the Christ; the Anointed One; the only Governor of his Church; and the Redeemer of All mankind. There is here an intimation that the Christian Church is to endure for ever; and the Christian ministry to last as long as time endures: He shall go no more out for ever.

Not sure what your point is. I did not say the Tetragrammaton is not important. It's just that we don't know how to pronounce it in Hebrew. I believe there is a reason for that and that is now, in this life, it is not important that we know how to pronounce it. What is important is that we call on the name of His Son Jesus so that we can be forgiven, indwelt by the Spirit of God and become a new creation in Christ. Calling on the name or person of Jehovah alone will not save anyone unless He first comes to the Son and allows the Son to reveal and give him access to the Father.
Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me. If you really knew me, you would know my Father as well. From now on, you do know him and have seen him." John 14:6
“All things have been committed to me by my Father. No one knows who the Son is except the Father, and no one knows who the Father is except the Son and those to whom the Son chooses to reveal him.” Luke 10:22
