The entity you refer to as father , God , I am , do not have the same attributes of Jehovah the Originator , Provider and sender of the prophets , The Judge of the Day of Judgement,,, Jehovah is self-sufficient without rivals he creates and is not created Jehovah feeds and is not fed. And Jehovah is not .000001% human.
That is true that Jehovah is not human at all for He is God,but Jesus said all things are possible with God,and nothing is too hard for Him,so He has the ability to manifest Himself in flesh.
It does not take away from His deity,for He still is an omnipresent Spirit,but Jesus is the fulness of the Godhead bodily,and the man Christ Jesus is the personal human body of God.
Gen 18:1 And the LORD appeared unto him in the plains of Mamre: and he sat in the tent door in the heat of the day;
Gen 18:2 And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,
Gen 18:13 And the LORD said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old?
Gen 18:14 Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.
Gen 18:17 And the LORD said, Shall I hide from Abraham that thing which I do;
Gen 18:18 Seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him?
Gen 18:19 For I know him, that he will command his children and his household after him, and they shall keep the way of the LORD, to do justice and judgment; that the LORD may bring upon Abraham that which he hath spoken of him.
Gen 18:20 And the LORD said, Because the cry of Sodom and Gomorrah is great, and because their sin is very grievous;
Gen 18:21 I will go down now, and see whether they have done altogether according to the cry of it, which is come unto me; and if not, I will know.
Gen 18:22 And the men turned their faces from thence, and went toward Sodom: but Abraham stood yet before the LORD.
God and 2 of His angels appeared in flesh before Abraham.
Gen 32:24 And Jacob was left alone; and there wrestled a man with him until the breaking of the day.
Gen 32:25 And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob's thigh was out of joint, as he wrestled with him.
Gen 32:26 And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.
Gen 32:27 And he said unto him, What is thy name? And he said, Jacob.
Gen 32:28 And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed.
Gen 32:29 And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there.
Gen 32:30 And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved.
Jdg 13:16 And the angel of the LORD said unto Manoah, Though thou detain me, I will not eat of thy bread: and if thou wilt offer a burnt offering, thou must offer it unto the LORD. For Manoah knew not that he was an angel of the LORD.
Jdg 13:17 And Manoah said unto the angel of the LORD, What is thy name, that when thy sayings come to pass we may do thee honour?
Jdg 13:18 And the angel of the LORD said unto him, Why askest thou thus after my name, seeing it is secret?
Jdg 13:19 So Manoah took a kid with a meat offering, and offered it upon a rock unto the LORD: and the angel did wondrously; and Manoah and his wife looked on.
Jdg 13:20 For it came to pass, when the flame went up toward heaven from off the altar, that the angel of the LORD ascended in the flame of the altar. And Manoah and his wife looked on it, and fell on their faces to the ground.
Jdg 13:21 But the angel of the LORD did no more appear to Manoah and to his wife. Then Manoah knew that he was an angel of the LORD.
Jdg 13:22 And Manoah said unto his wife, We shall surely die, because we have seen God.
How does one explain these manifestations of God.Notice how God says why ask for My name for it is secret when Jacob,and Monoah asked for His name,which a human and an angel would not have to say that in that way.
If a person does not believe God can be appear in flesh as Jesus,then they would have to not believe that God appeared to Abraham,and Jacob,and Samson's parents,that was in the Old Testament.
