Neither is Jesus being referred to as Yahweh in the OT or NT either but also no other believers are ever called "the one mediator between God and men, the man Christ Jesus" either.
Neither is there any other believe that it is specifically said of as the "foreknown" before the foundation of the world and as per 1 Peter 1:20.
Neither is does it state about any other believer "that all of the fullness of God dwells within them" either.
Therefore only through Jesus does one call upon the name of Yahweh!
By the way, don't you know the difference between calling on the name Yahweh and confessing the name Jesus Christ as kurios?
For you seem to be willingly ignorant and therefore confusing Romans 10:9-10 to say "that if you should call upon the name of Yahweh and believe in your heart that Yahweh has raised Yahweh from the dead, you shall be saved".
Also and once again Jesus said this below.
John 17:3 "This is eternal life, that they might know you (he was praying to Yahweh his Father) The Only True God and Jesus the Christ whom you have sent".
Also, your little ignorant attempt to get around this will never hold up at the end of the age, for God gave Jesus all of his words and Jesus said this more than once also and God is not so simple that he would have Jesus say something like this if it wasn't exactly what he meant him to say and especially not when our eternal life depends upon it.
This means that "The Father is The Only True God and Jesus is the Christ whom he sent" period and with nothing more to be added or removed from what Jesus stated either!
Nope, but instead, all call upon the name of Yahweh through confessing Jesus Christ as kurios and believing in their hearts that Yahweh raised him from the dead and just like Paul said in Romans 10:8-10 and this fulfills the prophecy of Joel that Paul mentions right after this in Romans 10:13.
For it is only through the Son that one calls upon the name of the Father Yahweh.
