How many times have we heard someone say, "I'll keep you in my prayers, bless her heart or I'll add you to our prayer list at church". You know they have forgotten it as soon as they walk away. This is basically what Matthew had to say about that.
"And don't say anything you don't mean. This counsel is embedded deep in our traditions. You only make things worse when you lay down a smoke screen of pious talk, saying 'I'll pray for you,' and never doing it, or saying 'God be with you'. and not meaning it. You don't make your words true by embellishing them with religious lace. In making your speech sound more religious, it becomes less true. Just say 'yes' and 'no'. When you manipulate words to get your own way, you are wrong.
