Jeremiah 1:5; "Before I formed thee in the belly I knew thee; and before thou comest forth out of the womb I sanctified thee, and I ordained thee a prophet of nations." 
God must have known Jeremiah from a prior existence!

Rev. 22:8 And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things. [9] Then saith he unto me, See thou do it not: for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God. 
How could the angel and the prophets be brothers, if it wasn't when they were both created, as spirit beings, prior to the prophets being born into this earth age?

Ephes. 1:5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, . Ephes. 1:6 To the praise of the glory of His grace, wherein He hath made us accepted in the Beloved.. [7] In whom we have redemption through His blood, the forgiveness of sins, according to the riches of his grace; [8] Wherein He hath abounded toward us in all wisdom and prudence;  [9] Having made known unto us the mystery of His will, according to His good pleasure which he hath purposed in himself
And
Romans 8:29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.  [30] Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.[31] What shall we then say to these things? If God be for us, who can be against us?
How come some of us don't have free will, but are predestinated to do certain things in this earth age, except God knew us from before?
Paul, for example, did not have free will! Paul's will was to kill Christians. Did Paul come forward at a alter call by his own free will? No, God just knocked him off his horse and said, your mine dude!

For as Paul documents in I Cor. 15 there are two bodies, one is of flesh and one is of spirit. So when you die in the flesh you are raised, shall we even say born again, into your spiritual body. 1 Cor. 15:44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. He goes on to say that unless you are born back into a spiritual body, you cannot literally enter into the kingdom of God. - You can be saved, by repentance and claiming the blood of Christ to cover your sins, but you must, at the death of your flesh body, or at Christ's return, (which ever happens first) be reborn into a new spiritual (celestial) body to literally enter Christ's kingdom.
 
In 1 Cor. 15:50 Paul says, "Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.

Now read, very carefully, what John records in chapter 3 of his book: Especially verse verses 3 & 13.

John 3:1  There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:
2  The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
3  Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.

Most people think Jesus is talking about being saved here.
He is not.
He is just telling us we were once spirit beings, with celestial bodies, but later brought into this earth age as human beings (flesh and blood persons) who must be born again back into spirit bodies to literally enter His kingdom at His return or when we die; which ever comes first.
Saved or not, we will all be born again, back into our celestial bodies!
We're not talking about immorality of our souls here, but type of body. 4  Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
5  Jesus answered, Verily, verily, I say unto thee, Except a man be born of water (flesh & blood, terrestrial body) and of the Spirit (back to spirit, celestial body), he cannot enter into the kingdom of God. 
6  That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7  Marvel not that I said unto thee, Ye must be born again. (back to spirit, celestial body)
8  The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
9  Nicodemus answered and said unto him, How can these things be?
10  Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
11  Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
John 3:11  Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
12  If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13  And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.

Nor ever will!
We all existed previously as spirit beings, with celestial bodies, (Yes, the body we must be re-born into) in heaven before being born here on earth in this flesh and blood, terrestrial body, but we must go back, be born again into our celestial body, after this flesh life ends.

Read again  what Jesus has to say to Nicodemus in John 3:3 "Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God." - Of course,flesh and blood cannot literally enter the kingdom of God. You must first be born back into your celestial bodies when this flesh and blood life ends and we are no longer in our terrestrial bodies. - Cremated, buried, blown apart or vaporized by a nuclear bomb, it doesn't matter. When you are through with the flesh body, you are through with it forever. And John 3:13 Jesus says, "And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven."

All of us must be born "from above", into the sack of water (terrestrial body)  and then be re-born of the spirit (back into our celestial body) in order to literally enter into the kingdom of God.

Isaiah 8:18
Behold, I and the children whom the LORD hath given me are for signs and for wonders in Israel from the LORD of hosts, which dwelleth in mount Zion.

Jesus Christ along with the elect of God, the ones chosen before the foundation of this earth age (Eph. 1:4), i.e. the ones the LORD had given Him, all serve His purpose, His will, and serve as conspicuous "signs" which means beacons, signals, lights, evidence, even as witnesses. Again, we already noted that Psalm 22:30-31 speaks concerning the "seed" who shall come (even have) and serve Him in this final generation. Those sons and daughters make up those two rays of light spoken of in Habakkuk 3, who are those two golden candlesticks in Rev. 2 & 3, who are the churches of Philadelphia and Smyrna.

Paul is now going to recap, as if to say "in others words", and then he will explain something else that Jesus Christ accomplished by His death, the depth of which is understood by those who have been eating "meat" for awhile!

Hebrews 2:14
Forasmuch then as the children are partakers of flesh and blood, He also himself likewise took part of the same; that through death He might destroy him that had the power of death, that is, the devil;

So... Jesus Christ took part of flesh and blood after the same manner as all the children of God who must all be "born again", which is to be born "anothen" meaning born "from above", into the sack of water and then be re-born of the spirit in order to enter into the kingdom of God. Christ explained this requirement to Nicodemus in John 3 and that "even the Son of man, who is now in heaven, was willing to do the same (John 3:13). It is also confirmed by the words of Paul in the 9th chapter of Hebrews where he teaches us that it is given unto all men once to die (i.e. in the flesh) before the day of judgment (which occurs at the end of the Millennium). Hebrews 9:27 "And as it is appointed unto men once to die, but after this the judgment." Again, Christ was willing to do the same thing as the children and so we see the love and fairness of our Father in that He did not ask His children to come down from above and be born of flesh while exempting Himself.

From Pamphlet #4201

My Note:  We were created before the earth Ref. Scripture Job 38:1-7

We, you and me, were all created before the earth existed.

Scripture:  Job 38:1  Then the LORD answered Job out of the whirlwind, and said,
2  Who is this that darkeneth counsel by words without knowledge?
3  Gird up now thy loins like a man; for I will demand of thee, and answer thou me.
4  Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
5  Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
6  Whereupon are the foundations thereof fastened? or who laid the corner stone thereof;
7  When the morning stars sang together, and all the sons of God shouted for joy?

Of course you must know that you were one of those morning stars to appreciate the statements made in verse seven. Remember Joseph's dream from Genesis 37:9.
We, just like Joseph and his eleven brother, are all stars of heaven. Yes, we've been there! Some of us still are, waiting our turn to come here and spend time in flesh and blood/animal bodies. Many of us have already been here and have returned to be with the Lord.
Read (live link-) to-Genesis 37:1-11.

Please note, I did not say the flesh body, you now live in, was created prior to Genesis 1:26.

Then as described in Genesis 1:1 God created the heavens and the earth as described in Job 38:1-7 when all of us sons of God shouted for joy when seeing the beautiful new home (earth) He had just created for us to live on.

But after that something bad happened; and we find the earth in ruins as described in Genesis 1:2.

1 John 5:6  This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth. 7  For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one. 8  And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one. 9  If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.

Romans 11:5-8 Even so then at this present time also there is a remnant according to the election of grace. [6] And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then is it no more grace: otherwise work is no more work. [7] What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded [8] (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day.
