Rom 8:30

8:30 Those predestined are, in due time, “called,” or effectively summoned through the gospel into saving fellowship with Christ (1:6; cf. 1 Cor. 1:9). We note that all of those “called” are also “justified.” The call cannot refer to the outward call of the gospel that many reject. It is an inward call of God that performs what He intends. All who are predestined are called in this way. Predestination includes God’s determination that a person will receive such an effective call (that is, the “effectual call”). Predestination is not based on God’s knowing beforehand how people will respond to the gospel. Just as the predestined are called, so the called are both justified and certain to be finally glorified. The past tense of “glorified” indicates that from God’s standpoint the work is as good as done. He will complete it as planned. See theological note “The Perseverance of the Saints.”
