Broadly speaking there have been two general views as to the meaning and use of the word “foreknew” in Romans 8:29.
One class of commentators (the Arminians) maintain that Paul is saying that God predestined to salvation those whom He foreknew would respond to His offer of grace (i.e., those whom He saw would of their own free will repent of their sins and believe the gospel).
Godet, in commenting on Romans 8:29, asks the question: “In what respect did God thus foreknow them?” and answers that they were “foreknown as sure to fulfill the conditions of salvation, viz. faith; so: foreknown as His by faith.” 1 The word "foreknew” is thus understood by Arminians to mean that God knew beforehand which sinners would believe, etc., and on the basis of this knowledge He predestined them unto salvation.
The other class of commentators (the Calvinists) reject the above view on two grounds.
First, because the Arminians’ interpretation is not in keeping with the meaning of Paul’s language
and second, because it is out of harmony with the system of doctrine taught in the rest of the Scriptures.
Calvinists contend that the passage teaches that God set His heart upon (i.e., foreknew) certain individuals; these He predestined or marked out to be saved.
Notice that the text does not say that God knew SOMETHING ABOUT particular individuals (that they would do this or that),
but it states that God knew the individuals THEMSELVES – those whom He knew He predestined to be made like Christ.
The word “foreknew” as used here is thus understood to be equivalent to “foreloved” – those who were the objects of God’s love, He marked out for salvation.
The questions raised by the two opposing interpretations are these: Did God look down through time and see that certain individuals would believe and thus predestine them unto salvation on the basis of this foreseen faith?
Or did God set His heart on certain individuals and because of His love for them predestine that they should be called and given faith in Christ by the Holy Spirit and thus be saved?
In other words, is the individual’s faith the cause or the result of God’s predestination?
A. The meaning of “foreknew” in Romans 8:29
God has always possessed perfect knowledge of all creatures and of all events.
There has never been a time when anything past, present, or future was not fully known to Him.*
But it is not His knowledge of future events (of what people would do, etc.) which is referred to in Romans 8:29,30,
for Paul clearly states that those whom He foreknew He predestined, He called, He justified, etc. Since all men are notpredestined, called, and justified,
it follows that all men were not foreknown by God in the sense spoken of in verse 29.
It is for this reason that the Arminians are forced to add some qualifying notion. They read into the passage some idea not contained in the language itself such as those whom He foreknew would believe etc.,
He predestined, called and justified. But according to the Biblical usage of the words “know,” “knew,” and “foreknew” there is not the least need to make such an addition, and since it is unnecessary, it is improper.
When the Bible speaks of God knowing particular individuals, it often means that He has special regard for them, that they are the objects of His affection and concern.
For example in Amos 3:2, God, speaking to Israel says,“You only have I known of all the families of the earth; therefore I will punish you for all your iniquities.” The Lord knows about all the families of the earth, but He knew Israel in a special way.*
They were His chosen people whom He had set His heart upon. See Deuteronomy 7:7,8; 10:15. Because Israel was His in a special sense He chastised them, cf. Hebrews 12:5,6.*
God, speaking to Jeremiah, said, “Before I formed you in the womb, I knew you,” (Jeremiah 1:5). The meaning here is not that God knew about Jeremiah but that He had a special regard for the prophet before He formed him in his mother’s womb. Jesus also used the word “knew” in the sense of personal, intimate awareness.
“On that day many will say to me, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?’ And then will I declare to them, ‘I never knew you; depart from me, you evildoers’ “ (Matt. 7:22,23).
Our Lord cannot be understood here as saying, I knew nothing about you, for it is quite evident that He knew all too much about them – their evil character and evil works;
hence, His meaning must be, I never knew you intimately nor personally, I never regarded you as the objects of my favor or love. Paul uses the word in the same way in I Corinthians 8:3, “But if one loves God, one is known by him,”
and also II Timothy 2:19, “the Lord knows those who are His.” The Lord knows about all men but He only knows those “who love Him, who are called according to His purpose” (Rom 8:28) – those who are His!
