I don't know that for me there is anything that is scary about predestination. Maybe because outside of Ephesians I was spiritually raised in a church that teaches about this, or maybe it's just having that assurance in Jesus that he is with me and I am with him. I know with my heart that I will go home to be with him at his coming. And that to me gives me security. I know that he predestined me for himself before the foundation of the world, and because of his grace I am saved. I know that he will continue a work in me through his spirit. I praise him for that, and because Paul had that assurance of his salvation through his relationship with Jesus how could he not praise him!?
