Philippians 2:13 answers that as do many other scriptures. You do not speak to the underlying “HOW”. That “how” is God.
Romans 8:29-30 states, “For whom He foreknew, He also predestined to become conformed to the image of His Son, that He might be the first-born among many brethren; and whom He predestined, these He also called; and whom He called, these He also justified; and whom He justified, these He also glorified.”
You have to go through extreme scriptural calisthenics to make that mean something other that what it really does.
I know that scripture well
