I don't read or understand it that way though. I say foreknew in that verse, given what follows (predestined, called, justified, glorified) plus many verses we see that contain words such as elect, called, chosen not only in relationship to the believer but through all the history of God working in His creation, as the One who chooses everything pertaining to salvation and leading to the cross, as meaning He knew them. Not what they would do in the future. One example would be Eph 1:4 For He chose us in Him before the creation of the world to be holy and blameless in His sight. In love He predestined us for adoption to Himself as sons through Jesus Christ, according to the purpose of His will, to the praise of His glorious grace, with which He has blessed us in the Beloved.
And before you announce again that we are not predestined as individuals to salvation but to be holy and blameless in His sight, you cannot separate those two things as not being the same thing. The one He chooses of necessity is holy and blameless in His sight. In a sense to change that meaning as many do, to mean that election is to holy and blameless, not salvation, is to have works begin to infringe upon grace.
To say that foreknew means He looked into the future in His omniscience and saw who would choose Christ, and then chose them, and then predestinates them to holiness, is to say that His entire plan of salvation is based on contingencies. People do something and then and only then will He do something. It also completely changes the true meaning of both choose and predestinate.
