Beginning on Sunday the reflections aim to encourage an Advent for all.
The first reflection states that: "Life may seem humdrum, but God's plan could break in at any time.
"We don't know which will come first - Christ's return (Second Coming), or our death, but we need to live each day as if tomorrow is already here - because one day, we'll be right."
#Advent is here! Read my first Sunday of Advent reflection. It's about 'Vigilant Waiting'. https://t.co/ngKZoAVSnv

The Archbishop's online reflections are an accompaniment to a book written by Tom Wright 'Advent for Everyone - a journey through Matthew' which the Archbishop commended as his Advent Book for 2016.
Dr John Sentamu said: "I love Advent - it's a wonderful season of watching and waiting."
