Winkelbury Camp is an Iron Age hill fort in Wiltshire, England. According to legend, if you march around it at midnight cursing all the time you can summon the Devil who will appear on a black horse and grant one wish. Of course, that's a foolish superstition. In the first place you cannot summon Satan to come to you. In the second place you need not summon Satan to come to you, for he is always near. Most importantly, Satan never gives, he only takes. The superstitions that surround Satan should not lead us to suppose that all is superstition. We know only a little about the Devil. The doctrine of evil is not fully developed in Scripture. We do know this; temptation is always around us and always to be resisted.
