God said he knew Jeremiah before he was born. Now, if I understand Ares Man's concept of God's foreknowledge, this would mean Jeremiah existed before he was born. I do not believe the scriptures show this whatsoever.
On the other hand, if God's foreknowledge simply means that God can see through all time at once, he could see that Jeremiah would believe and be a man of great faith and obey all that God commanded him. And I believe this is what the scriptures show.
Jer 1:1 The words of Jeremiah the son of Hilkiah, of the priests that were in Anathoth in the land of Benjamin:
2 To whom the word of the LORD came in the days of Josiah the son of Amon king of Judah, in the thirteenth year of his reign.
3 It came also in the days of Jehoiakim the son of Josiah king of Judah, unto the end of the eleventh year of Zedekiah the son of Josiah king of Judah, unto the carrying away of Jerusalem captive in the fifth month.
4 Then the word of the LORD came unto me, saying,
5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.
6 Then said I, Ah, Lord GOD! behold, I cannot speak: for I am a child.
7 But the LORD said unto me, Say not, I am a child: for thou shalt go to all that I shall send thee, and whatsoever I command thee thou shalt speak.
8 Be not afraid of their faces: for I am with thee to deliver thee, saith the LORD.
9 Then the LORD put forth his hand, and touched my mouth. And the LORD said unto me, Behold, I have put my words in thy mouth.
10 See, I have this day set thee over the nations and over the kingdoms, to root out, and to pull down, and to destroy, and to throw down, to build, and to plant.
Ares Man almost seems to suggest that the elect existed before they were born into this world, that they had a previous relationship with God before the foundation of the world. I personally do not believe this.
God does say in verse 5 that he knew Jeremiah before he formed him in his mother's womb. To me, this simply is showing God's foreknowledge. God could see that Jeremiah would believe God's word when he heard it.
We notice that Jeremiah did not receive God's word until this day. God's word is spirit, so I believe this is the day the Holy Spirit was poured upon Jeremiah.
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
And notice in verse 10 it says "this day" have I set you over the nations and kingdoms.
So, I do not believe that Jeremiah had the Spirit until this day. He did not have a relationship with God before this. I believe he knew Jeremiah would be a very faithful believer and so chose him to be a prophet.
And to answer Old Regular that said when the scriptures say Jesus knew from the beginning who would believe that this only meant from when his ministry started is silly. Jesus knew all that he had to do from his youth.
Luke 2:42 And when he was twelve years old, they went up to Jerusalem after the custom of the feast.
43 And when they had fulfilled the days, as they returned, the child Jesus tarried behind in Jerusalem; and Joseph and his mother knew not of it.
44 But they, supposing him to have been in the company, went a day's journey; and they sought him among their kinsfolk and acquaintance.
45 And when they found him not, they turned back again to Jerusalem, seeking him.
46 And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.
47 And all that heard him were astonished at his understanding and answers.
48 And when they saw him, they were amazed: and his mother said unto him, Son, why hast thou thus dealt with us? behold, thy father and I have sought thee sorrowing.
49 And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
50 And they understood not the saying which he spake unto them.
Jesus knew everything he must do and his ministry from the very beginning, it didn't suddenly occur to him when his ministry began.
And John 6:65 says Jesus knew from the beginning who would betray him. The scriptures spoke of Judas betraying Jesus hundreds of years before he was born.
John 13:18 I speak not of you all: I know whom I have chosen: but that the scripture may be fulfilled, He that eateth bread with me hath lifted up his heel against me.
19 Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
Jesus here shows that he knew which of his disciples would believe beforehand, and he knew that Judas would not.
Ares Man seems to suggest that the elect had some sort of relationship with God before the foundation of the world. But notice in verse 19 Jesus speaks of Judas betraying him, and shows that it had not yet come to pass. That is, the Lord knew things that will occur in the future, it is not saying that things had pre-existed before the foundation of the world.
So, this is not scriptural. There are many scriptures that shows that Jesus knew who would believe and who would not beforehand.
