Nothing states that Abraham saw the LORD's face, but that the LORD did appear unto him by the name of God Almighty, which is Adonai, or Lord, as a man. Find the phrase God the Father in the Scripture, and you should realize that "God the Father" isn't a name or title for a certain entity apart from the Word and Holy Ghost, but that God (the Father, the Word and the Holy Ghost) is the Father of all (that have eternal life) is the meaning of that phrase.

1Co 8:6 But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.

Whenever you see God in Scripture, that is speaking of also the Word and the Holy Ghost in all instances and God is the Father. However, the Son is another matter. The Father is the Father of the Son, not the Word, the Father is the Word, which is the answer to Christ's question in Matt 22, which Art never bothered to answer because he can't viewing things the way he does. Jesus is the Word and the Son, he is the Father and the Holy Ghost for he is also the Word, yet he as the Son is not the Father, for God is a Spirit and not a man, but Jesus himself is Jehovah Saves, Joshua, he is Jehovah and the same that passed by Moses and the same that appeared to Abraham with two angels.

I am not your teacher and only wish to share things with you that you may in turn try them by your own knowledge of the Lord. I really don't know any thing. Still learning and growing in the knowledge of our Lord and Savior Jesus Christ. Praying for you and all men that you would also come to the knowledge of the truth and continue to grow in it. I am a sinner, but I have a hope that God through Jesus Christ our Lord will deliver me from my present situation of being a sinner and deliver me from this vile body and I thank him for this promise of eternal life. This is my faith that I share with all my brethren in the Lord who we patiently wait for. Jesus Christ IS come in the flesh.

Rom 8:22-25  For we know that the whole creation groaneth and travaileth in pain together until now. And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body. For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for? But if we hope for that we see not, then do we with patience wait for it.
