There is nothings as good as peace and as bad as disputes.
David declared "Seek peace and pursue it (Psalm 34:15).
The Sages comment, “Seek peace for your loved ones and pursue it for your enemies; seek peace where you live and pursue it elsewhere; seek peace with your body and pursue it with your resources; seek peace for yourself and pursue it for others; seek peace today and pursue it tomorrow.’’
This final exhortation means that one should never despair of making peace; rather he should pursue it today, and then tomorrow and then the next day...until he attains it.
If thick ropes which pull a wagon are strained regularly they will become weak, and eventually will tear. So it is with strife. If one does not succeed in making peace on his first or second attempt, nevertheless, he should not abandon his pursuit of this sacred achievement. Ultimately his words will accomplish. If he will have no effect at all on the quarrelers, because they have become overpowered by the appetite for triumph and are blind to the truth, he may be able to influence those who have been drawn into a quarrel that is not their own. In this way he will save them from the bitter retribution which results from strife, in the way of Moses who saved Ohn and Korach's sons. [Chofetz Chaim]
By perservereance and patience one can beat all impossible odds even when one thinks they can't do it and all seems hopeless - where there's a will there is always a way.
We should understand that peace and loving others run along the same lines. How is that? Because it’s only through loving others that one could guarantee that there will always be peace among them. This could be learned from Ethics Of Our Fathers, 1;12 which states “Be among the disciples of Aaron, loving peace, pursuing peace and loving others.” Why does it state “loving peace” - what’s the connection to peace? The answer is that as a result of loving and pursuing peace one will come to love his fellow beings. This should be every man and woman's deepest and truest strivings.
