Lose job, sickness, unwanted divorce. Not talking about cursing. Back up what you say by what you do. Oaths should be unnecessary. Plainness of speech.
Promises are like money - easier made than kept.
No glue fixes broken promises. In the heat of the moment we make vows we can't keep. There is power for victory through the cross. Be slow to anger. Grill a good steak - close lid and restrict oxygen flow.
