“for by your own words you will be acquitted, and by your own words you will be condemned.”
There is a verse (or more) that refers to never letting praise depart your lips. Thhis verse from Matthew brings that to mind. I also reminded of the Shema, if we tke Yeshua’s words here seriously, then it is wise to make sure that we make sure that “These words, which I am ordering you today, are to be on your heart; and you are to teach them carefully to your children. You are to talk about them when you sit at home, when you are traveling on the road, when you lie down and when you get up. Tie them on your hand as a sign, put them at the front of a headband around your forehead, and write them on the door-frames of your house and on your gates.” – Deuteronomy 6:6-9
How you do that is up to you, but I would advocate learning to say the Shema after waking and before bed. Daily and nightly study is good, too. You have to find what works best for you and I’m sure that will change time by time. Clearly it is important that we guard our hearts, filling them with goodness, so that only good comes out of them as we speak.
