Don’t argue for your own weaknesses. When you make a mistake, admit it, correct it, and learn from it immediately. (Stephen R. Covey, author of The 7 Habits of Highly Effective People)
It must be human nature. When we show our weaknesses by making mistakes—and we all do—we make excuses. We blame circumstances, other people, or faulty equipment—anything to put the blame someplace else. Many of us have learned, however, that we get past those difficult times best when we acknowledge our errors and move on purposefully.
I do not have time to tell about [more Old Testament heroes] . . . who through faith conquered kingdoms . . . whose weakness was turned to strength; and who became powerful in battle and routed foreign armies (Hebrews 11:32-34).
