I am very much indebted to my son, a priest, who a number of times has offered this quote to me for my reflection. It has helped me to make efforts to think much before speaking much and to be a respecter of persons. (1Peter 2:17 ,1Peter 5:15).
I also have seen my son apply this rule himself and I believe that it has helped him to be a respected and loved pastor.
I’ve found it’s helpful to say, “I don’t understand what you mean.”
