Thy will be done
If we can’t say “thy will be done” from the bottom of our hearts, we will never know any peace. We will feel compelled to try to control people and control our environment and make things the way we believe they ought to be. Yet to control life like this is beyond our abilities, and we will just dash ourselves upon the rocks. This is why Calvin adds that to pray “thy will be done” is to submit not only our wills to God but even our feelings, so that we do not become despondent, bitter, and hardened by the things that befall us.
— Tim Keller (in Prayer)
