Satan and demons don't have to tell you what they will do! They do have to have your permission to get into your life, but they will never be honest about it! They will trick and lie at every opportunity, presenting every opportunity to give them an in by saying this is harmless, your family will benefit from the money, it's just a game, you can stop any time, people will make fun of you if you don't do this, etc. So you say, just this once, fortune telling is a joke, the boss won't miss a few dollars, etc. And you did what they wanted, but they never told you they were going to take over your life from that little toehold.
