This is probably one of those questions one may not really have given any thought and just assume Adam and Eve have seen God. But if we explore the scriptures once more let us see what is revealed.
* In The Garden *
And they heard the voice of the Lord God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the Lord God amongst the trees of the garden. Genesis 3:8 KJV
In the book of Genesis we read that Adam used to walk with the Lord God in the cool of the day. Have you ever noticed the scripture says “Lord” God. This was one of the things that caught my eye because sometimes the Bible says Lord God and other times it may say God. Could this be a way to show us there is a difference? If we look at several scriptures it is mentioned no one has seen the Father.
No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him. John 1:18 KJV
According to the account of the Apostle John it appears no man has seen God at any time. It does make reference the Son has declared him but nothing else.
No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us. 1 John 4:12
Again another reference is made from the Apostle John stating no man has seen God at any time. This would include Adam and Eve. So who were they walking with in the cool of the day? The answer to this would be Jesus, the “Lord” God.
There are teachings which say Moses spoke to God personally. But do we know it is the Lord God or God the Father. For one thing if we think it is God the Father it would go against the scriptures we just read. No man means no man. It doesn’t mean no man except Adam. Wouldn’t you agree?
* Burning Bush*
Now Moses kept the flock of Jethro his father in law, the priest of Midian: and he led the flock to the backside of the desert, and came to the mountain of God, even to Horeb. And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed. Exodus 3:1-2 KJV
Notice the scripture says “the angel of the Lord” appeared unto Moses in the flame of fire. It was not God the Father.
These words the Lord spake unto all your assembly in the mount out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. And he wrote them in two tables of stone, and delivered them unto me. Deuteronomy 5:22 KJV
This among many other accounts shows us the Lord spoke to Moses in the midst of the fire. It was not God the Father. What does the Bible tell is in regards to someone seeing God? It says that no one can see his face and live.
And he said, Thou canst not see my face: for there shall no man see me, and live. And the Lord said, Behold, there is a place by me, and thou shalt stand upon a rock: And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by: And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen. Exodus 33:20-23 KJV
When we read these scriptures we need to first recognize they make reference to “the Lord”. We can see a pattern forming when the Bible says “the Lord” and the “Lord God” are the same. We must remember it was Jesus who would manifest himself in the Old Testament. God the Father spoke to his people but it would not be his actual presence.
In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1 KJV
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. John 1:14 KJV
The Word was with God and the Word dwelt among us. We know without a doubt Jesus walked on earth in the New Testament. He showed the world the heart of God with the miraculous things he would do. Moses and many others in the Old Testament saw the Word before it became flesh.
