Jesus is YHWH in the OT, He is/was also one of the persons in the plural "Elohim" that means "God", Plural means, and where it says of Elohim in the very beginning, "Let "US" make/create/do this or that... The Son is/was an aspect of God/Elohim in the very beginning, The Son is also YHWH, Which YHWH had the the spirit of The Father, and the Holy Spirit, in him, inside of him, the Son, which is who what walked and talked with Adam & Eve, that is the Son, the Son as YHWH was not completely omniscient like his Father, the Spirit of the Father, that was in him was/is, No one has heard the Father's voice, or seen him at any time, man or angel, they only saw the Son as God, the spirit of the Father, that was in the Son, only spoke to him, alone, no one else...
If you examine YHWH in the OT, I think it is pretty evident that he was not completely omniscient, but was partially, which is much more than can be said of us, YHWH is the Son, and if you examine the OT, he acts much like a man does, but he is God, YHWH/the Son is love, and his acts in the OT, and as a man in the NT, by which we can see his growth and development and learning process, He has always been trying to "save" us, and what we see of him as a man was one final act to try and do this, and after that, he would not try to do it anymore, or do anything more, his final act, presented us with a choice, to believe in and follow him and believe in what he says and be doing it, or not... He knew that some would, and some would not, for he gave-up on trying to force them all (in the OT, probably because it was driving him crazy)...
Jesus was "The" Son of Man before he was baptized, after he was baptized, "The" Son of God, after he died, and was resurrected and ascended, He went to where the Father, His Father is, The Son is destined to become and take the place of The Father, at some point between his ascension and his returning to us, point being, by the time he gets back, He will be like the Father is and probably is like he is now, which no one knows, no men or angels, but him (The Son, who became/becomes as the Father is)...
"No one can come to the Father, except through me..." Jesus said this, by "No one can come to" that is "know" the Father, except through, that is, first knowing him, who he is now, by first knowing, who he was (God in the OT) and then, first knowing that first, coming to know who he is now (which is still a mystery, for he is like the Father now) Knowing "all" of this is the one and only way to know who the Father truly is and always was... For he, (The Son) is like the Father now...
If you want the short answer: God is, always has been and "is" Love... If you truly know what this is and means and if your honest and admit you don't fully yet, you/I can only come to know this through him (Christ, God in the OT, God/Man in the NT) First and by and only "after" knowing who the Son is, can you come to know who the Father is and always was, that is, What Christ is now...
The Father wanted the Son to be God, and so, let him be God, for this was the Father's desire and job, to let the Son be God and "teach" him and show him what he (The Father) is like through his (The Sons experience as God and also as a man) and by his (The Sons) experience, showing the Son, who he (The Father) once was before he became The Father, perhaps in another creation with his Father, when he was a Son, before he became a Father... Christ will take the Father's place one day, if it hasn't already happened, when this happens, The Father will move on and go to another place, that probably only he alone knows about, Like his Father before him did, when he took his place and finished that creation, and then began a new creation with his own Son, and showed his Son what he once had to go through when he was a Son with his Father before him, and ect., ect., so on and so forth, cycle of life... And our God, the Son, when this creation ends, will create a new one with his own Son, and ect. ect., so on, and so forth...
God Bless!
