"Behold, O my people, I will open your graves." When God wants to show you what human nature is like apart from Himself, He has to show it you in yourself. If the Spirit of God has given you a vision of what you are apart from the grace of God (and He only does it when His Spirit is at work), you know there is no criminal who is half so bad in actuality as you know yourself to be in possibility. My "grave" has been opened by God and "I know that in me (that is, in my flesh) dwelleth no good thing." God's Spirit continually reveals what human nature is like apart from His grace.
