Everyone who has been chosen of God in Christ before the foundation[Eph 1:4] will be in due time recipient of the Spirits sanctifying work so that He sets them apart unto belief of the Truth 2 Thess 2:13. Thats why Paul calls it also the Faith of Gods Elect that acknowledges the Truth Titus 1:1
Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God's elect, and the acknowledging of the truth which is after godliness;
Acknowledging the Truth and Belief of the Truth are the same, so all of Gods Elect will in Gods time acknowledge the truth. 36
