Advent reminds me of snow in that Jesus' coming ends up making our crimson red sins as white as snow. Believing and receiving this gift gives us far more than we bargain for. We may think we're getting "heaven" for someday, but we end up getting a new life beginning now. And it's a life in which there is a washing of new birth after which there are regular cleansings. Sin continues to be a factor for us in this present existence in Jesus. It is something we have to be aware of and sensitive to, if we're to really begin to understand and appreciate God's grace to us, in Jesus.
As the angel told Joseph,
It is important for us to remember that in Jesus' very name is a crucial part of the reason why he was born on that wonderful night. It's a reason that's important in our lives and together, in this world, everyday of our lives. It gives us hope, not only for beyond, but in this life. For this we give him thanks!
[Mary] will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.
