I read this passage in Isaiah today and I thought of a recent experience with my dad.
Last month we took our Paige, Michael, and their little boy to visit my parents. I learned that my dad had prepared for our visit by walking his large property, clearing paths for the little two-year old. He tried to find any obstacle that could cause a fall and removed little sticks and rocks. He went before his great-grandson and made the crooked places straight.
Somehow this makes me trust that God is removing obstacles on my path, too. He is preparing the way for good things to come.
