A friend has this huge dog, named Brody, tied up in his yard. One day Brody was sound asleep and two little puppies were walking by and came up into his yard. My friend hollered "Brody!" and the huge dog woke up and started barking really loud.

 The two little dogs took off running as fast as their little legs could carry them. They didn't realize the big dog was tethered and couldn't get at them unless they got closer.

It made me think of Satan, and how he can't get at us either, unless we get too close and/or let him.

During New Testament times, when Jesus walked the earth, Satan and his demons could enter a person and dwell in them and cause great

suffering. Jesus healed many of the people during that time and cast out the demons. But since His church began, Satan has to have our permission to dwell in us, and many are willing to give him that permission.
Zechariah 13: 1 In that day there shall be a fountain opened to the house of David and to the inhabitants of Jerusalem for sin and for uncleanness.
2 And it shall come to pass in that day, saith the LORD of hosts, that I will cut off the names of the idols out of the land, and they shall no more be remembered: and also I will cause the prophets and the unclean spirit to pass out of the land.
