Esther 9:22 - As the days wherein the Jews rested from their enemies, and the month which was turned unto them from sorrow to joy, and from mourning into a good day: that they should make them days of feasting and joy, and of sending portions one to another, and gifts to the poor.

While Memorial Day reminds us of those who have fallen for our country, it is still a joyous day. It is a day to rejoice in the freedom we enjoy as Americans, and to remember and thank God for those who have given all for us to have that freedom.
