Hanukkah began at sundown on Tuesday night (Kislev 25) and runs for eight days. This is a feast that is fitting for all believers in the One True God to celebrate, a celebration of God’s miraculous intervention!! Jesus Himself celebrated this “Festival of Lights” in his time on earth, and the Gospel of John mentions it on John 10:22. In this season of Advent, when we prepare for the coming of Jesus and are reminded of the darkness of the world before His coming — who is Himself the Light of the world (John 1:4-5; 8:12)– celebrating or at least appreciating Hanukkah is ultimately a celebration of Messiah Jesus, who came shining brightly in His incarnation!
(Check out the apocryphal books of Maccabees (e.g. 1 Mac. 4:56-59; 2 Mac. 10:5-6) for the whole story… and remember that these books can have value to us even if not on the par with the rest of the canon of scripture… no time now to hash through that issue!)
