Job 14:4: Who can bring a clean thing out of an unclean? not one
Job, in his frustration, means that God wants to hold him to a standard of perfection, when he is but an imperfect mortal. The impure often can be made pure, through prescribed ritual actions, but nothing can make man immortal or perfect. Furthermore, God could have made man perfect, if He had chosen to do so. Because God has established things such that things reproduce after their kind. Since Adam and Eve were sinners, their children, who were born after their nature, were also sinners. So because Adam and Eve became sinners, all of their descendants are sinners (which is the whole human race) because unclean people cannot produce clean people, but only more uncleanliness. Job accused God of trailing him to see if he was going to fail. He claimed God was tallying his sins and not forgetting or forgiving them. He said God was putting them all in a bag and saving them for judgment.
Job is correct, though, in that only God can create the unclean. Both personal and social life can only flourish when grounded on the atoning blood of Jesus Christ. True social order cannot be gained by either guns or butter, nor even by the elective process. If every nation were to tomorrow adopt the Republican form of civil government, or any other elective form of civil order, the results all over the world would be no different than they are now or would be the same within a year or two. The problem is within man and it is sin.
