Craig R. Brown:
God is much greater than we can possibly imagine. A deity so powerful that He can allow His creatures to make free choices, yet determine from the foundation of time what those choices will be, leaves us in total awe. This truth should make us want to fall on our knees in total praise and submission to Him.
At the same time, this truth should bring tears of thankfulness to our eyes. It is nearly incomprehensible that a God this powerful loved you and me enough not only to choose us from the beginning of time, but also to work all things together for our good. Only an all-powerful God could do this. (The Five Dilemmas of Calvinism)
