I've always thought O Christmas Tree was a cheesy song. Don't get me wrong, I love Christmas trees, I just think that if you're going to write a song about them, you could at least make it creative. However, I looked up the lyrics tonight and it struck me:
O Christmas tree, O Christmas tree, with faithful leaves unchanging Your boughs are green, in summers' glow and do not fade in winters' snow.
It's just like God's love for us.
