Satan loves quite, shy people. He has a list of these people and next to their name is checked the box that says: “No threat!”
He assigns special agents to these people. These agents keep the cold hateful waters of this dark world and the twisted beliefs of this world on them so that they forever stay away from the possibility of igniting for Christ.
If someone becomes outspoken and develops a fighting will still Satan need not worry. All he has to do is to make sure his agents get them to fight for a cause that is of no value to Gods kingdom, or better yet one that goes against Gods kingdom. Then that one who now fights is not just a non threat status but becomes an ally to Satan and his agenda.
