Simplest thing in the world!!!! In all things: GOD MOVES FIRST. God never "Reacts".Is your existence due to first your parents choice to come together and have you, then God reacts to their choice by creating you?
Is your existence due to first Gods choice to create you, and Gods determined means to bring you into existence was your parents choosing to come together and have you?
Bonus question: Where does your grandparents choice, to have your parents, fall in the logical order of your existence?
