What if there are very valid reasons for why he doesn't prevent the devil from causing and spreading human suffering?
What if you were a parent of a beloved child with a life threatening genetic defect and the doctors told you that the only way to permanently fix it was with a series of very painful surgeries over many years? Would your first concern be the pain....or the end result of what caused that pain? Think about that before answering.....
Why do you think there is this "roaring lion" in the first place? You do understand that God did not create the devil...he is entirely self-made. Just as a murderer or a thief is not born a murderer or thief, but chooses to become one by the exercise if his own free will.....so the devil made himself a "slanderer" (devil) by calling God a liar, and a resister (satan) by abusing his free will and becoming God's adversary. What possible reason could God have for not dispatching him immediately?
God will restrain satan shortly, but not until he is finished with him. There is so much more to this story than you think.
The big picture is amazing PoD, but not many are taught to see it. They seem to be left staring at a few dead pixels and scratching their heads.
The next thing, they pointing fingers at God and accusing him of not caring.....nothing could be further from the truth.
