Did you know the name Y'shua (Yeshua) means "Yahweh is salvation" in Hebrew? Y'shua is the only Heavenly Entity who has the Name of YHWH (Yahweh) within His own name! The angels/messengers all have the title of Elohim (God) within their names: Michael, Raphael, Gabriel....
Take a look at the powerful words Yeshua speaks right here, which amply reveal that He and His Father are ONE:
John 14:10 Don't you believe that I am in my Father and my Father is in me? These words that I speak, I do not speak of myself but He who dwells in me, my Father does these works. 11. Believe that I am in my Father and my Father is in me; otherwise believe even because of the works. 12. Amen, amen I say to you that whoever believes in me, these works that I do, he will do also, and more than these he will do because I go to the Father. 13. And whatever you ask in my name, I will do for you that the Father might be glorified by His Son. 14. And if you ask of me, in my name, I will do it! 15. If you love me, keep my Commandments. 16. And I will ask of my Father and He will give you another Redeemer who will be with you forever. 17. The Spirit of Truth, He who the world is not able to receive because it has not seen Him, nor does know Him. But you know Him for He dwells with you and He is in you. (AENT)
The Name above all Names, however, is YHWH ("Yahweh"):
John 17: 11. Henceforth, I will not be in the world, and these are in the world. And I am coming to Your presence. Kadosh Father, keep them by your Name, that which you have given to me, that they may be one as We are. 12. I was with them while I was in the world. I have kept them in your Name; those whom you have given to me, I have kept. And not a man of them is lost except for the son of perdition, that the Scriptures might be fulfilled. 13. And now I come to Your presence, and these things I speak in the world that my joy may be full in them. 14. I have given to them Your Word and the world hates them because they are not of the world as I am not of the world. (AENT)
 Kadosh/Set Apart means that YHWH and His Word will never change; we can put our trust in Him knowing He will keep His Word.
 A very key passage. Aramaic literally reads that YHWH gave His Name to Y'shua; therefore, he has the Name of his Father within him.
 Y'shua keeps them in YHWH's name so when we call upon YHWH in Y'shua's name, we are calling on YHWH for Salvation. As the Name of YHWH is in Mashiyach, so are we to have the name of Mashiyach in us, which means that as followers of Y'shua we are to walk according to his righteousness, observe Torah and walk in the anointing of the Ruach haKodesh as Mashiyach demonstrated to us.
In view of the above, to call upon Y'shua (who was our Final SIN offering - He martyred Himself) is to call upon YHWH to save you!
(NOTE: Our use of the term "martyr" is intentional because traditional Jews love to point out that "G-d never required human sacrifice!" Well, Y'shua wasn't a "human sacrifice" because nobody "sacrificed" Him. He was a Divine Sacrifice who willingly went to the cross/stake. As a human being, He had the choice to obey YHWH or not. As we see time and time again, He CHOSE to obey. He KNEW who He was....)
Philippians 2:9-11 says: "Therefore Elohim exalted him to the highest place and gave him the name that is above every name, and that at the name of Y'shua every knee should bow in heaven and on earth and under the earth, and every tongue confess that Y'shua is YHWH, to the glory of the Father."
Hebrews 1:4 also teaches that the glory always goes to YHWH, but "the name that is above all names" is YHWH. The reason - as mentioned above, is that the names of angels/messengers have EL in them (short for the title of "Elohim"). EL is a title for YHWH, but not His Name!
Take a look at this powerful passage:
John 17:11 "I will remain in the world no longer, but they are still in the world, and I am coming to you. Holy Father, protect them by the power of Your Name - the same name you gave me - so that they may be one as we are one."
How about that? Even the Greek New Testament reads this way, proclaiming that the "name of Y'shua" is really that of YHWH. Therefore, every time we lift up our voices to Y'shua, we are actually proclaiming praise to the One and only YHWH; literally, to the glory of the Father. Furthermore, since there is only One Name for the One Elohim, those who call on the true Name of YHWH become one with Y'shua, which then makes them one with YHWH. So, to bring it all together we can confidently:
(1) Pray in the name of YHWH.
(2) Ask for the power of YHWH's promises in the name of Y'shua as the method of their fulfillment, but only as a way to bring glory to YHWH. This involves, by the way, performing miracles. Take the case in Acts 4:1-12. In that passage, Jews who witnessed the miracles of Peter and Yochanan were not content to hear that they simply came from Elohim. Instead, they wanted to specifically know by what name it was done.
Peter says it was by the name of Y'shua the Mashiyach of Nazareth that a lame man was healed. However, Peter is careful to make the point that YHWH Himself raised Y'shua from the dead so that this power could be accessed when he believed the same thing. So, when he adds in verse 12, "For there is no name under heaven given to men by which we must be saved," he is not saying that Y'shua the man replaces YHWH. Rather, what Peter means is that there is no other Mashiyach that Elohim has chosen except Y'shua to fulfill YHWH's promise. To say the Name of Y'shua, is to acknowledge the power of YHWH to save us according to His Word.
(3) Immerse in the name of the Father (YHWH, Who promised and sent the Son), in the name of the Son (Y'shua, who fulfilled YHWH's promise) and the Set Apart Spirit (who is the "spirit of truth" that gives you the reasons behind the ritual). Reason: For only in that manner are the complete methods of fulfilling that promise recognized (Ezekiel 36:23-27), with all the glory again to YHWH. The Aramaic word for this carries a meaning closer to "immersion", as in using Jewish ritual mikveh baths. Also, the fact is that Ruach haKodesh (Set Apart Spirit) is another name for YHWH (Psalm 51:11) and the Mashiyach has the Divine Nature within him that only comes from YHWH (Isaiah 11:1-2, 1 Corinthians 12:3).
(4) Assemble in the Name of Y'shua (YAH - SHUA...."YHWH is Salvation"): "When two or more gather in my name, there I am in the midst," refers to these days when Mashiyach has physically departed from the world. He resurrected and ascended to "the right hand of the Father." This is a metaphor that means "to dwell next to the Father" (Psalm 110:1).
So, remembering that Yochanan (John) told us about the Word made flesh that was with Elohim in the beginning (also see Yochanan 17:5), what happens after ascension is that Y'shua becomes the Word again! We know this because when He comes out of heaven again He is called by the name that he took on when He entered it two millennia before: Word of Elohim -Revelation 19:13! Therefore, since the Word is with YHWH again, they are inseparable, and to gather in that Name is to gather in the Name of YHWH, while accessing the power of the promise of His Mashiyach.
