Successes are an answer to all criticism
Reflecting on the Mexican-American War in general and the taking of the City of Mexico in particular, Ulysses S. Grant -- who was not in command of the army -- mused about he might have done things differently than General Scott. Then Grant offers this piece of wisdom:
“But my later experience has taught me two lessons: first, that things are seen plainer after the events have occurred; second, that the most confident critics are generally those who know the least about the matter criticised....But General Scott’s successes are an answer to all criticism.”
God tells us that "good sense is a fountain of life to him who has it" (Proverbs 16:22). The future president recognized that good sense reserves judgement, handles critics wisely, and lets success do the talking. Lord, give me that good sense today.
