To lead others, you have to be much quicker to forgive. Your impulse, like most people’s, is to hold a grudge and remain frustrated with the other person, but what has that ever accomplished? It’s never righted a wrong or mended a relationship. There’s no point in trying it.
Forgiveness, on the other hand, allows situations to improve. That’s not to say forgiveness is a cure-all for any sort of conflict, but it is an important step to take. If nothing else, you should forgive because it’s what you would want for yourself. Often, the moments when you need to forgive someone are the same moments you should be saying sorry to someone else. Would you not want them to accept your apology? Would you not hope for mercy from others?
