What is true of each of the persons whom God

God has "called" that individual. Notice that the elect are not predestined to be saved, they are predestined to be in the image of Christ.

Although all Heaven is blessed and rejoices when a sinner repents and returns to the Father’s house, it remains true that God’s eternal purpose has not been fulfilled when we receive the Lord and have our sins forgiven. The Divine purpose has been accomplished only when we have been fashioned into the image of the Lord Jesus Christ.

Notice also the past tense of the verbs employed in Romans 8:30: He "called"; He "justified"; He "glorified." Before He created the universe God saw each of His sons as called, as justified, as glorified. God already views you and me in the state of glorification. Let us therefore give diligence to make our calling and election certain.
