"Zechariah saw Joshua the high priest standing before the presence of God in the holy of holies- but Joshua's garment were covered in excrement. He was absolutely defiled. Zechariah couldn't believe his eyes. Ray said the key interpretive question is: How could that have happened? there's no way that the Israelites would ever have allowed the high priest to appear before God like that. Ray answer was this, God was giving Zechariah a prophetic vision so that he could see us the way that God sees us. In spite of all our efforts to be pure, to be good, to be moral, to cleanse ourselves, God sees out hearts, and our hearts are full of filth. "
