Since our son has grown up and his family now have their own Christmas traditions, my husband has often asked me why I want to bother with a Christmas tree and all the trimmings.
Truthfully, this is usually said just after he collapses in his chair (huffing and puffing) from bringing in the tree, boxes of decorations, and tangled strings of lights out of the storage building in the backyard.
Candy canes symbolize the shepherd's crook, which helps the shepherd gather lost and strayed sheep. The candy cane can also be turned upside down to stand for the letter 'J' in Jesus. The red and white coloring is for Christ's blood and purity.
Gifts beneath the Christmas tree remind us how we have received the greatest gift through the blood of Jesus Christ. They also remind us that charity brings love and we should always share with those around us.
