You can never make the same mistake twice because the second time you make it, it isn’t a mistake; it’s a choice. (Michael Baisden, radio personality)
No one is above making mistakes. We all do it. An honest mistake should not discredit an otherwise truthful person. But, if people repeat their mistakes, you might question their sincerity. When you become aware of your mistake, you have the responsibility to correct it and, even more importantly, not to intentionally repeat it.
Have I not written . . . sayings of counsel and knowledge, teaching you to be honest and to speak the truth? (Proverbs 20:20-21)
