“Obedience unites us so closely to God that in a way transforms us into Him, so that we have no other will but His. If obedience is lacking, even prayer cannot be pleasing to God.”
St. Thomas Aquinas

For Reflection:
Why do I think prayer is not pleasing to God without obedience? Where have I been disobedient to God in the past, or now presently? To what extent have I seen my disobedience affect my prayer?
