Tomorrow at Redeemer we're focusing on the incarnation via Matthew 1:18-25. Here are some words from Edwards on the birth of Jesus.
Christ’s incarnation was a greater and more wonderful thing than ever had yet come to pass. The creation of the world was a very great thing, but not so great as the incarnation of Christ. It was a great thing for God to make the creature, but not so great as for the Creator himself to become a creature. We have spoken of many great things that were accomplished between the fall of man and the incarnation of Christ: but God becoming man was greater than all. Then the greatest person was born that ever was or ever will be.
