I have just finished reading Trystan Owain Hughes' "Real God in the Real World" which has taken me through Advent and Christmas, offering a daily Bible reading and reflection.
There have been some helpful reflective challenges in there. He ends with a reflection on our tendency to worry, reminding me that I once heard our time described as 'the age of anxiety'. Like all feelings and emotions, worry does have its place - but it shouldn't be an overwhelming place as sometimes feels to be the case.
God doesn't offer to remove our worries - as some sometimes claim - but what God does is to offer to walk with us. As Hughes comments: "The incarnation reassures us that God knows what it is like to have the cares of the world on our shoulders, and he truly wants us to offload those cares on to him."
