Obviously God knew in eternity past who He was going to choose unto Salvation in Jesus Christ. He would not be God if He did not. Foreknowledge of God in election has nothing to do with God knowing who, of their own freewill, would believe or refuse to believe. If that were true He would not have foreknowledge since, according to you Arminians, He would have to wait while you shuffled your feet trying to decide whether you wanted to believe or not. Furthermore, man of his own freewill will never believe to the saving of his soul.
One further point Winman. You keep accusing those of us believe in the Biblical Doctrines of Grace of believing men, not the Bible. You apparently believe that you are the inerrant interpreter of Scripture. That is sheer arrogance on your part. You would do well to understand that you are not the inerrant interpreter of Scripture. Realizing this you might be inclined to read what others say about Scripture, recognizing that God may have revealed an understanding of some parts of Scripture to others that He did not choose to reveal to you.
1 Peter 1:20 clearly says that we are "elect according to the foreknowledge of God the Father". I agree with you, God does not make mistakes. And God has told us here that his Election is based on something he foreknew. And I have showed you scripture that says Jesus knew "from the beginning" who would believe not. Therefore he also knows who will believe.
The concept you cannot grasp here is that God having foreknowledge of what will happen does not determine what will happen. If a man remains in and dies in unbelief, God knows it. But if that man at some point repents and trusts Christ, God knows that as well.
This does not violate God's sovereignty. He can still bring about his will regardless of the circumstance. I showed that before in other posts, a clear example is in Esther.
Est 4:13 Then Mordecai commanded to answer Esther, Think not with thyself that thou shalt escape in the king's house, more than all the Jews.
14 For if thou altogether holdest thy peace at this time, then shall there enlargement and deliverance arise to the Jews from another place; but thou and thy father's house shall be destroyed: and who knoweth whether thou art come to the kingdom for such a time as this?
In this story, evil Haman who hated Mordecai the Jew had convinced king Ahasuerus to pass a law allowing all the people of the land to kill the Jews on an appointed day. Mordecai requested that queen Esther go before the king on the Jews behalf.
But look what Mordecai says, he says that if queen Esther does not go before the king, "then shall there enlargement and deliverance arise to the Jews from another place". In other words, events are not locked in stone, but God can bring about his will regardless.
Now, no man can understand this, but I believe this shows that God knows all possible outcomes in advance. Did he know that queen Esther would go into the king? Yes. But what if queen Esther did not go in, would he know that? Yes. And he would have chosen someone else to deliver the Jews.
But back to the subject. God knows in advance who will believe and who will not. That is not my opinion, that is what the scriptures clearly show.
John 6:64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
Now, I included verse 65 which is a favorite of those that argue that God imposes faith on a man. But this verse is clearly used out of context by Calvinists. Notice I highlighted the word "it". To understand this verse, you have to know what that "it" is. And if you read the whole chapter you will see Jesus is speaking of the word of God.
John 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
Here is another favorite verse used by Calvinists. But again, you cannot pull it out of context, it is explained further in the chapter.
John 6:39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
Another favorite verse of Calvinists, but read on.
John 6:44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
Yet another favorite verse of Calvinists. But now all of these verses are explained. The very next verse shows how God draws a man.
John 6:45 It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
Here Jesus shows how a man is drawn to God. It is through the scriptures. Before a person can come to God, they have to be "taught of God". It does not say they are regenerated to believe. And Jesus says every man that has "heard and learned" of the Father, cometh unto me.
So, you are not regenerated to believe. You hear the word of God and believe, just as Romans 10:17 says.
And Jesus explains this again later in the same chapter.
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.
64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
65 And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
Here Jesus explains that his words are spirit and they are life. To be saved, you have to receive and believe Jesus's words, the scriptures. In John it shows that Jesus himself is the Word of God.
John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Rev 19:13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
When Jesus says that no man can come to God unless it were given him of the Father, he is speaking of the scriptures, of the Word of God. Without the scriptures we would not know of God, we would not know of Jesus, and would not be able to place our faith in him. And this is what Paul says in Romans.
Rom 10:14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
So, you can't pull scripture out of context. In John chapter 6 Jesus is speaking of the scriptures, of the Word of God. This is how a man is saved, by hearing and believeing the gospel.
And to answer your last statement, I do not believe myself to the the "inerrant interpreter" of scripture. It is simply that I believe (and have shown) literally dozens of verses of scripture that contradict Calvinism. I believe that any saved person can understand the scriptures if he will ask God's help.
James 1:5 If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him.
I always pray and ask God to help me understand the scriptures. I am fully aware that I am a fallible man and could easily make mistakes. But I take the scriptures very seriously, and also am fearful. I also pray always that I do not misrepresent the scriptures, and ask forgiveness if I have.
So, I do not have this sort of proud attitude at all, and I am being sincere.
