Be Holy as I'm Holy meaning God is one with his Word so we are to be Holy by being One with his Word thus being one with God because the Word was with God and the Word is God!!! (JESUS IS THE WORD THE word spoken into time when God said let there be light and the Holy Spirit moved and there was light or illumination in the firmament before the Sun was created because the Son was already existing.

Joh 1:1-17 KJV 1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made. 4 In him was life; and the life was the light of men. 5 And the light shineth in darkness; and the darkness comprehended it not. 6 There was a man sent from God, whose name was John. 7 The same came for a witness, to bear witness of the Light, that all men through him might believe. 8 He was not that Light, but was sent to bear witness of that Light. 9 That was the true Light, which lighteth every man that cometh into the world. 10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. 14 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. 15 John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh after me is preferred before me: for he was before me. 16 And of his fulness have all we received, and grace for grace. 17 For the law was given by Moses, but grace and truth came by Jesus Christ.

Which I believe was the plan the whole time Jesus was literally born to die so that light could enter the dark world and save our souls from sin and give us salvation. Adam, whom is the man God formed out of the dust of the earth and then God breathed the breath of lifes into so that mankind can exist. I say the breath of lives because we already existed in Spirit realm but needed a body.

Also because the Word of God says God knew us before we were in our mothers womb therefore

Jeremiah 1 1

"Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations." "Ah, Sovereign LORD," I said, "I do not know how to speak; I am only a child."

Adam was created from the dust of the earth and Eve formed out of man using a rib bone.. thus the verse bone of my bone flesh of flesh comes to mind which is why marriage is so sacred and should be cherished because it was God's intentions for man to not be alone or All one!!! So Adam "knew" his wife meaning that had relations and Eve conceived their children.  Which is why God made the flesh and breathed lives in it that our  Spirit could have a home and be birthed out of the flesh so we could co-exist in the spirit and the natural at the same time because a spirit needs a host.

Genesis proves this to us by saying

Gen 1:26-28 KJV 26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. 27 So God created man in his own image, in the image of God created he him; male and female created he them. 28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.

So man became a living flesh with mind will emotion  or our soul after God breathed the breath of lives in us so that life as we know could  Perpetuate or continue replen
