On the 14th day of the month of Adar at sunset begins the celebration of Purim. Purim lasts two days from sunset to sunset each day.
Purim began when we were outside of Jerusalem and exiled by God. Esther, by the hand of Yah, rescued our people from death and persecution by finding good favor from the King Ahasuerus with help from Mordecai. This is an Appointed Time that was not given to us in the Law of Moses yet it still testifies of the Messiah. In Esther 8:8, Esther is given the authority to overturn a law that condemned all Jews to death. Likewise, Yahushua (who is also called Jesus) was given all authority to remove the condemnation of the Law of Moses and to be the author of salvation for all that obey Him (Hebrews 5:9).
On Purim, we give gifts to each other and the poor in celebration of the gift of life from the Most High. It should be a day of good eating and fun with our brothers and sisters in the faith while sharing what God has blessed us with, with those who need it most (Esther 9:22).
