The Before (pro) and From (apo’)

Eph 1:4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:

1Pe 1:20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,

From–

The Lamb Slain From The Foundation of the World is-
The first man Adam – Christ was in Adam slain
It is the whole material creation because it is material and visible to the natural man and must pass away

Joh 1:1-16
(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.
Eph 3:9
(9)  And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:

Did we behold His glory?

Heb 10:20 By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh;

The Veil (the flesh, the first man Adam) keeps us from seeing Christ

2Co 3:13-16
(13)  And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:
(14)  But their minds were blinded: for until this day remaineth the same vail untaken away in the reading of the old testament; which vail is done away in Christ.
(15)  But even unto this day, when Moses is read, the vail is upon their heart.
(16)  Nevertheless when it shall turn to the Lord, the vail shall be taken away.

Known Him as the Vail

2Co 5:16 Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more.

Mar 15:37-38
(37)  And Jesus cried with a loud voice, and gave up the ghost.
(38)  And the veil of the temple was rent in twain from the top to the bottom.

In the Image of God
Gen 1:27 So God created man in his own image, in the image of God created he him; male and female created he them.

The Head comes forth first – the body follows
Col 1:15-19
(15)  Who is the image of the invisible God, the firstborn of every creature:
(16)  For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
(17)  And he is before all things, and by him all things consist.
(18)  And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
(19)  For it pleased the Father that in him should all fulness dwell;

Through our offenses

(25)  WhoG3739 was deliveredG3860 forG1223 ourG2257 offences, G3900 andG2532 was raised againG1453 forG1223 ourG2257 justification. G1347

(11)  For we which live are alway delivered unto death for Jesus’ sake, that the life also of Jesus might be made manifest in our mortal flesh.

The Lamb was slain in his body
Rom 6:5-6
(5)  For if we have been planted together in the likeness of his death (Lamb slain from the foundation), we shall be also in the likeness of his resurrection:(The Lamb worthy to open the book)
(6)  Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.

Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?

1Pe 4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin; (suffering is the result of ceasing from sin because we are made sin)

Not offering and sacrifice but a body

Heb 10:5-9
(5)  Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me:
(6)  In burnt offerings and sacrifices for sin thou hast had no pleasure.
(7)  Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
(8)  Above when he said, Sacrifice and offering and burnt offerings and offering for sin thou wouldest not, neither hadst pleasure therein; which are offered by the law;
(9)  Then said he, Lo, I come to do thy will, O God. He taketh away the first, that he may establish the second.

Eph 5:30 For we are members of his body, of his flesh, and of his bones.

Volume of the books

Rev 20:12 And I saw the dead, small and great, stand before God; and the books (Psa 139:16 the slain lamb) were opened: and another book was opened, which is the book of (the) life (of the Lamb{ as it HAD been slain Rev 5:6}): and the dead were judged out of those things which were written in the books, according to their works.
