Scripture says the Magi laid their treasures at the feet of Jesus. What treasures of yours would you lay at his feet of the newborn king? Your perfected virtues? Your vices (sometimes our vices are our treasures!)? Think about it.
Our treasures are those things which we most value. And sometimes the things we most value, and most want to retain are our sins and vices. Like any treasure, sometimes the things we most want to keep for ourselves are the very things we need to surrender.
So, to put it in an odd way, give Jesus the "treasure" of your sins this year. Lay that "treasure" at the feet of Jesus in the manger, and then walk away from them, asking Jesus to keep them and to bring them to the cross with him when he gets there.
