Discipline yourself and stand guard at the door of your heart. Don't follow everyone blindly. Be selective. There are pages you shouldn't like, groups you shouldn't belong to, except you're there as an ambassador of Christ, doing what your father did in the house of a tax collector. "Its just for fun", they will tell you but there is a hidden agenda, a device by the devil to destroy young minds.
The devil is everywhere and he's not there for fun. He is earnestly doing something dangerous to the souls of men. Don't hesitate to make use of the exit button because it may be your only way to free your soul.
Parents, teachers and care givers should make sure that the supervise their children on the use of social media. Some kids have gone to strip clubs and brothels. They've seen what you did not see. But all these under your own roof/watch. You have to wake up and save their own soul.
The devil is advancing just as technology is advancing. He uses what is prevalent and what people like in each era to populate his kingdom. You may see it just as fun but there are forces, energies or spirits interacting with your spirit man. You must be selective in your interactions. If need be, unfriend and un follow someone. Use the exit button in some groups to save your soul. And don't forget that some friends are like CCTV.
