I understand your religious belief but I wish you could see that you present it in a way which does not prove fruitful. Your first claim is that certain verses "have details that are not clear in the text."
Some might say, "no, they have the details that are clear, but you read in other ideas because you need the verses to say more." Others might say, "the details that are not clear are not at all what you think they are but since they are not clear, you miss them" while even others might say, "the details are clear if you read the text properly and in the right context."
Your next suggestion is that 7:14 has to do with a "virgin birth". That is no where in the verse and is a function of what you need to find, after the fact.
Then you say that something is "clear from the text." Thing is, no such thing is clear to many people. What is clear is that you are using eisegesis, starting from the conclusions you need to validate.
There are plenty of things I could say are "clear from the text" and I could either show you the explanations which show how clear they are, or I could just aver their truth with nothing other than my faith to support them. Neither would prove persuasive.
The Tanakh talks about God being a Savior. This verse from the Old Testament is also in the Tanakh.
Isaiah 45:18-23 KJV Bible Gateway passage: Isaiah 45:18-23 - King James Version
18 For thus saith the Lord that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the Lord; and there is none else.
19 I have not spoken in secret, in a dark place of the earth: I said not unto the seed of Jacob, Seek ye me in vain: I the Lord speak righteousness, I declare things that are right.
20 Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that set up the wood of their graven image, and pray unto a god that cannot save.
21 Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the Lord? and there is no God else beside me; a just God and a Saviour; there is none beside me.
22 Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.
23 I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.
