There is a well known ancient Arabic parable about a man, his camel, and a tent. In the story the man and his camel are traveling in the desert. The man stops for the night and sets up his tent, then gets in and beds down because the temperature is cold. Shortly, the camel asks to put his snout in the tent because it is so cold outside. The man allows it, but tells the camel he must put just his nose in as the tent is only big enough for one. Soon the camel asks to put his front hooves in. The man, being considerate, reluctantly allows that as well. Finally, the camel asks to put his hind hooves in, arguing that he will freeze and not be able to continue the journey in the morning. As ridiculous as it sounds, the man allows the camel’s third move. Upon putting his hind hooves into the tent, the camel pulls his whole body in and the man is pushed out of his tent completely. The devil works this way as well. In fact, you probably intuitively understand this. If you give in to one temptation, then it is easier to give into another. Then, sooner than you’d care to admit, a chain of events has occurred, and you are beholden to sins you never thought you’d agree to.
This is particularly troublesome for someone who doesn’t truly follow Jesus. Consider the boy in Mark 9:14-29. An evil spirit possesses his body, taking such control over it that it prevents him from speaking or hearing. It also throws his body to the ground and into fire trying to harm or kill him. Thankfully, Jesus casts the demon out and the boy is restored. Why are these stories so troublesome for a non-Christian? Because of Jesus’ warning in Matthew 12:43-45. Jesus describes how if demons are cast out of one home, they can return to it. In that passage he talks about how a single demon is cast from a home. The home is then cleaned, but when the demon returns and finds the house in order, yet unoccupied, he brings 7 more demons with him and they re-invade the house so that it’s new possession is worse than its first. But if Jesus occupies that house, those demons won’t be able to get in. They may bang on the house, they may sit on the lawn and shout at the windows, but they won’t be able to live in it.
So let the one person live in your house that won’t allow Satan to put his nose in.And if you are already a Christian don’t even let Satan on your lawn unless you want him banging on your door.
