Jesus is our Mediator to approach God the Father. YHWH God did not require any mediator

The mediator between God and men is one

"And in none other is there salvation: for neither is there any other name under heaven, that is given among men, wherein we must be saved." Acts 4:12 ASV

Since from the beginning YHWH has been known as the only Savior, Redeemer of Israel, it means that Jesus is YHWH in flesh because of the statement of Acts 4:12 cannot imply that Jesus is another Savior but the only Savior. Because Acts 4:12 is a strong rebuke of the false teachings of the Antichrist who denies Jesus as YHWH in flesh, he orders his agent to teach that Jesus is some kind of a zombie who does the job for YHWH, who carries the title for YHWH but cannot be the actual YHWH. Even the second of Jesus is taught to be the coming of YHWH and not of Jesus, even though we will see Jesus, because Jesus does the will of YHWH, because Revelation 1:8 identifies Jesus as EL-SHADDAY, the God of Abraham, Isaac, and Jacob, but who is known as YHWH from Moses until He changes His name again.

He that overcometh, I will make him a pillar in the temple of my God, and he shall go out thence no more: and I will write upon him the name of my God, and the name of the city of my God, the new Jerusalem, which cometh down out of heaven from my God, and mine own new name. Revelation 3:12 ASV

What is the name of the Father of Jesus? We do not know it but if we overcome Jesus will write the name of His God on us. That does not sound like YHWH.

"and they shall see his face; and his name [shall be] on their foreheads." Revelation 22:4 ASV

"All things have been delivered unto me of my Father: and no one knoweth who the Son is, save the Father; and who the Father is, save the Son, and he to whomsoever the Son willeth to reveal him." Luke 10:22 ASV

"And I saw, and behold, the Lamb standing on the mount Zion, and with him a hundred and forty and four thousand, having his name, and the name of his Father, written on their foreheads." Revelation 14:1 ASV

1 Timothy 2:5 Murdock

For God is one; and the mediator between God and men is one, namely the man Jesus the Messiah;

2

Hebrews 8:6 Murdock

But now, Jesus the Messiah hath received a ministry which is better than that: as also the covenant, of which he is made the Mediator, is better, and is given with better promises than the former.

3

Hebrews 9:15 Murdock

And for this reason he became the Mediator of the new covenant, that he might by his death be redemption, to them who had transgressed the first covenant; so that they, who are called to the eternal inheritance, might receive the promise.

Hebrews 12:24 Murdock

and to Jesus, the Mediator of the new covenant; and to the sprinkling, of his blood, which speaketh better than that of Abel.

DOES THE SACRIFICE OF JESUS MAKE SENSE IF MAN ALWAYS HAD ACCESS TO JEHOVAH GOD?

If Jehovah God called for Adam and Eve who hid themselves in the garden of Eden because they their newly acquired godly power rested upon them the shame of being naked and they heard Him and Jehovah chatted with them.

If Jehovah God chatted with Cain because he killed his brother.

If Jehovah God found Abraham and appeared to him in various forms and visions.

If Jehovah God appeared to Isaac and Jacob.

If Jehovah God appeared to Moses. If He spoke to Moses face to face. If Moses even saw His back. If He descended to Sinai to speak to the former slaves to the point they were scared to death and rather commissioned Moses to be their mediator between them and Jehovah God.

Then, what sense does it make for Jesus to leave Heavens to become flesh and die in order to be the Mediator between Jehovah God and man, to reconcile man to Jehovah God, so that no man can go to Jehovah God but only through Jesus? Because before Jesus man did not need any such special representation to get access to Jehovah nor Jehovah to approach man. Jehovah even spoke face to face to Abraham.

The advent of Jesus has disturbed the theology of Judaism because Jesus had insinuated that He is YHWH God. Jesus also introduced the existence of a new God in Judaism Whom He calls Father.

Above all, Romans 10:9 and Philippians 2:9-11 make the confession that Jesus is Jehovah the Most High mandatory for salvation.
