Lovecraft depicts Cthulhu as a gigantic entity worshiped by cultists. Cthulhu's appearance is described as looking like an octopus, a dragon and a caricature of human form. Its name was given to the Lovecraft-inspired universe where it and its fellow entities existed, the Cthulhu Mythos.
Once people realize that the root of the enacted law is the moral law, that the root of the moral law is the design of the created order, and that the root of the created order is the Creator, they are only one short step from understanding what happens when the roots of law are severed.
All law-breaking brings separation between God and the sinner (Isaiah 59:2) and results in death (Rom. 6:23). So, to be under the Law means that the person is obligated to keep that Law in all its aspects (Deut. 27:26), and if he does not the Law condemns him. The problem is that we are not able to keep the Law perfectly, and any infraction results in a necessary judgment.
