He who never made a mistake never made a discovery. (Samuel Smiles, 19th-century Scottish author)
Mistakes just come with being a human. We’d like to be perfect, and we regret our mistakes, but they happen. That’s why there are erasers on pencils and spell-checks in our word processors. It might be interesting to study inventions and improvements that have been initiated by a mistake in an earnest attempt to achieve some good. When you blunder, get up and keep working.
Indeed, we all make many mistakes (James 3:2). The godly may trip seven times, but they will get up again (Proverbs 24:16).
