Everything has its season, and there is a time for everything under the heaven:
A time to be born and a time to die;
a time to plant and a time to uproot the planted.
A time to kill and time to heal;
a time to wreck and a time to build.
A time to weep and a time to laugh;
a time to wail and a time to dance.
A time to scatter stones and a time to gather stones;
a time to embrace and a time to shun embraces.
A time to seek and a time to lose;
a time to keep and a time to discard.
A time to rend and a time to mend;
a time to be silent and a time to speak.
A time to love and a time to hate;
a time for war and time for peace.
Due to our time in the exile, we have assimilated the ideas of the goyim. We have learned from them the distortion of truth that says destroying, killing, hate and war are always bad and building, healing, love and peace are always good.
This is wrong! There is a time and a place for everything even hate and war. It isn't easy. We, the Jewish people, have inherited our innate nature of chesed from our father Avraham. Just as Avraham suppressed his nature of chesed to fulfill the will of HaKadosh Baruch Hu, so must we. We must struggle every moment of every day to discern what is expected of us, by Hashem, in any given circumstance. We can't just follow our hearts like the goyim. We must learn Torah and study the words of our Sages, daven for wisdom and guidance so we know exactly how to act or react.
