Though we are Gentile (not of Jewish blood), as Christians we believe our Christianity can be greatly illuminated by learning about the festivals and feasts. As explained by Jeris Cribbs in "HANUKKAH--A Festival of LIGHT to the World!" Jesus is portrayed prophetically in the feasts and festivals, and though we are not required to observe or celebrate these festivals and feasts, it's a joy to see Jesus pictured in them.
We began celebrating Chanukah several years ago, when we became aware of learning about our Jewish roots. We are, after all, grafted in according to Romans 11:19, "...branches were broken off that I might be grafted in." With this new understanding, we began to look into participating in some of the Jewish festivals and feasts. Not in a ritualistic way, not to pretend to be Jewish, but to share in the revelation and blessing that is ours through Jesus.
To begin our celebration of Chanukah, we enjoyed a Chanukah tea:

Some of the elements you see above we learned about in books like the one displayed, Enter His Gates to Your Jewish Roots by Susan Marcus (still having trouble creating a clickable image, despite very kindly help in doing so...there must be a black hole in my brain when it comes to this HTML code stuff):

Chanukah begins this evening and lasts for 8 days. Tonight we'll light the first candle on the Chanukiah (the special candle holder or candelabrum--seen at our tea above) recite the traditional blessings, and play dreidl. At some point in the eight days we'll make latkes, read books about Chanukah and play dreidl some more.
We don't immerse ourselves in the celebration, as Advent and preparing for Christmas is our central focus, but we don't want to ignore it, either. Our lives are enriched by celebrating Chanukah in our own simple ways, and for us it only enlarges our perspective of Jesus and His coming.
