In marriage for example, you say 'Yes' on the day you get married, 'I do', but each day you implicitly if not explicitly, also say 'Yes', by every act that one performs in a marriage, one is saying 'Yes', making a cup of coffee for one's wife or husband is a form of saying 'Yes' to the marriage vow that one is continuing the marriage by affirming it in one's deeds. And exactly the same in the religious life.
