3. Really celebrate Jesus.
See? An easy one! Celebrate Advent in your house. Take your kids shopping for needy families, instead of for themselves. Give them money to put in the Salvation Army boxes. Put a nativity scene in your yard (or better yet, your living room). Talk about Hanukkah when it comes around, and what it means for both Jews and Christians. Read Luke 2 & The Gift of the Magi on Christmas Eve. Go to a Christmas Eve service. And so on, and on, and on...
Jesus is not the reason for the season, for the Christian; Jesus is The Reason. For everything. We don't have to put Christ in Christmas if he is already a year-round part of our lives.
May the Lord bless and keep you as you celebrate today and every day.
