The people of God in Isaiah’s time had blinded their minds’ ability to see God by looking on the face of idols. But Isaiah made them look up at the heavens; that is, he made them begin to use their power to think and to visualize correctly. If we are children of God, we have a tremendous treasure in nature and will realize that it is holy and sacred. We will see God reaching out to us in every wind that blows, every sunrise and sunset, every cloud in the sky, every flower that blooms, and every leaf that fades, if we will only begin to use our blinded thinking to visualize it.
