An emotionally empty environment will lead to bad consequences FOR THAT VERY REASON. It is emotionally empty. Nothing means anything. By playing
actual,
normal games the consequences of falling out of a tree or tripping over a skipping rope or even the embarrassment of missing your turn in musical chairs are felt in the real world. It's a valuable learning arena. Without it (such as in videogames) values having no basis in reality take over creating an empty heart ready for devils to move in.
But it's not enough to just start jumping rope or building an
actual tree house or sewing
real dolls clothes. Devils can invade all those activities. The important thing is turning to Jesus.
Luke 11:24-26 When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest; and finding none, he saith, I will return unto my house whence I came out. And when he cometh, he findeth it swept and garnished. Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.
