There are still armies that invade and suppress people. There are still germs that invade bodies. There is still sin in the world and in our lives. The world isn't what it should be. Our lives aren't what we would like them to be.
Nothing seems to have changed.
There are still hills and valleys and crooked and rough roads. Many people do not see God's salvation. Often people miss God's salvation because they are looking in the wrong places. They want to see a powerful military leader or a great physician. The savior is a baby in a manger.
