This view of sin as corruption, vileness, and filth is…

““This view of sin as corruption, vileness, and filth is symbolically portrayed in Zechariah 3:1-4: Then he showed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right side to accuse him. The Lord said to Satan, “The Lord rebuke you, Satan! The Lord, who has chosen Jerusalem, rebuke you! Is not this man a burning stick snatched from the fire?” Now Joshua was dressed in filthy clothes as he stood before the angel. The angel said to those who were standing before him, “Take off his filthy clothes.” Then he said to Joshua, “See, I have taken away your sin, and I will put rich garments on you.” Note who is described here. It is not a portrayal of the prodigal son, but of Joshua the high priest — the person holding the highest religious office in all Israel. Yet he is shown dressed in filthy clothes, a pictorial representation of both his sins and the sins of the people he represented as high priest. The filthiness of his garments depicts not the guilt of his sin but its pollution. Like Joshua, all of us are, in a spiritual sense, dressed in filthy clothes. We are not just guilty before God; we are also corrupted in our natures, polluted and vile before Him. We need forgiveness and cleansing.””
