Abner called out to Joab, "Must the sword devour forever? Don't you realize that this will end in bitterness? How long before you order your men to stop pursuing their brothers?" 2 Samuel 2:26
There comes a point in every battle when the questions are raised: "Is it worth it to continue? Will this only end in bitterness?" If continuing a pursuit will end in bitterness, why would we choose it? But if continuing will result in unity and strength, quitting isn't an option.
Some of the best advice a parent can hear is to pick your battles. However, just as important is to understand when it is time to say, "Okay! This has gone on long enough, and neither will benefit if it continues."
Lord, there are battles in life that I'm tired of fighting. Yet I know they must be continued. If the enemy is allowed to occupy certain places within me, there is no hope for seeing Your kingdom established. But if I am seeking to win for my own prideful gain, help me to put a stop to the pursuit. Help me to know the difference.
