When the Church historically spoke of the coming again of the Lord, it always thought of the the great day of judgment.
During Advent it is good to spend time thinking about God coming in the midst of evil and in the midst of death. He judges the evil in the world, and he judges it in us. And in judging it, he loves us, purifies us, transforms us and comes to us with his grace and love.
And that, if we accept it, can make us happy as only little children can be happy.
So…… “Do not be afraid. I bring you good news of great joy that will be for all the people. Today in the town of David a Savior has been born to you. He is Christ the Lord.
