The law of prayer - the law of belief - the law of life. The way we pray and worship has relation to what we believe (our faith) which also has relation to how we live our lives. It is not a one way relationship between the three as it can be noted that how we live our lives can certainly have an influence on how we pray and believe.
It can become easy to "forget" where we are, and who we are in the presence of when we attend Mass. It becomes even more difficult when others surrounding us forget. When a priest forgets efforts can be burdensome to say the least. This all can have an effect on not only our faith, but our daily life.
