Esther 9:28 And that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor the memorial of them perish from their seed.
The Feast of Purim was instituted as an annual observance to remember God’s salvation of His people and victory over their enemies. This memorial was to be kept as long as the Jews live on earth. God’s people respond to God’s great acts of Deliverance by celebrating and remembering what God has done for them. The yearly Feast was established so that they would never forget God or His mercies, but always remember.
Biblically, to remember is to call to mind and consciousness something from the past and make it active and operative in the present moment. We celebrate the Lord’s Supper in remembrance of Jesus and what He did for us. Daily we remember our Baptism by repentance and faith. We make the life, death, and resurrection of Christ active and real in this day. In a real sense, every day is a Festival keeping us mindful of God and His mercies.
