See, how you have to have a permissive will placed in so you will not God the one responsible for sin. In other words, it is the individual who is permitted to use his own will to choose
In order for you to stay anywhere near the Bible you have to pretend that God is not directly responsible for sin
D, when we look at Job with purely human eyes we see a man hit by incredibly "bad luck" someone that must have made very poor choices Yet we can see these events with spiritual eyes because God allows us to .
God was behind all of it..He controlled the parameters of the affliction. Through this series of "trials" Job grew in patience.
Even Satan is bound by Gods will so God can use even Satan's deeds for His purposes.
God has the ability to stop sin and does not..instead He allows man the freedom to sin without His restraining Grace.He allows man to bring damnation on Himself.
