God, by his foreknowledge, Psalms 53:2-3, saw that none would seek him, no, not one. Out of those that would not seek him, is the group that he choose a portion off before the foundation of the world and predestined them to be adopted as his children by Jesus Christ. The children did not choose God, but he choose them. Jesus paid the adoption price on the cross for those that God choose, and will complete the adoption process, when he comes back at the last day to gather his elect, and takes them home. We use this same adoption process in our society today.
