Have you ever noticed how fast infection spreads throughout the whole body? If you don't wash a cut; (gods word) and then if the infection is not gone, it will need antibiotic; (gods chastisement, as a father chastises a son) Then if it does not go away; amputation! The mild infection, over time and without proper care has turned to gangarene! and so the offending limb must be terminated and cut off from the body to save the rest of the body (or you get blood poisoning and die horribly).
I feel i must explain more because you claim to have studied in one end and out the other so i better not have you misunderstanding this example also. If sin is not wiped out by whatever measure has to be taken it will spread throughout the whole neighborhood, town, city, state, province and will never stop. Furthermore and deeper, just to mess you up . Since the first dispensation by god was according to the flesh(ly ways of man) the second dispensation of god is according to the spirit of God(ly ways). This is actually why people are not dying in huge numbers in every town, city, state, because sin is in the camp, because God has changed the dispensation of killing to cleanse and has given mankind over to themselves to work out their own salvation or way back to god by themselves. This is the grace of god, and a little deeper, since you understand the bible so well The grace of god will end because of an old saying that god purported 2000 yrs ago and more. "my spirit will not always struggle with man.. ". Therefore God will once more, shift the dispensation to gods wrath and you will appreciate this way more better because you understand gods wrath and hatred of sin more than anybody.
God bless
