Picture the scene - You are at a wedding and everyone is excited and chatting away in the Chapel. Suddenly the minister walks to the front and says: "The Bride is on her way. She is almost here!"
The mood immediately changes and people have now become extra expectant - your minds begin to race and these could be some of your thoughts:
"She is on her way!
It will be any minute now.
This is what we came here for!"
Isn't this also the same for Advent? This is what we are waiting for:
I am sending my messenger to prepare the way before me, and the Lord whom you
seek will suddenly come to his temple. The messenger of the covenant in whom
you delight— indeed, he is coming, says the Lord
of hosts" - Malachi 3:1
