We come to worship at Advent, and these are the first words we hear: ‘Comfort, O comfort my people, says your God.’ After a time of suffering and pain, the most uncomfortable of times, when the grass has withered from the earth, the world’s flower has faded, God wants us to know that he is coming to create new beginnings. And, to tell the world that this good news is coming, God is commissioning his messengers. Today we hear from Isaiah and from Mark. The book of Isaiah and the Gospel of Mark were written in, and describe, deeply uncomfortable times. They are both books of prophecy, for, like Isaiah, Jesus was a great prophet of his time.
