Role-playing is similar to visualization. It can be a worthwhile technique but it can also be harmful. A basic yardstick in deciding its value is the content of the role-playing situation. Psalm:101:3 says, “I will set no wicked thing before mine eyes.” If it’s questionable or evil (playing a sorcerer, for instance, in Dungeons and Dragons, which is occult), the effect very likely will be spiritually destructive and even demonic. On the other hand, if the role-playing content has no particular moral consequences (for example, rehearsing a job interview with someone), it may prove very helpful. But role-playing games almost always include extreme violence, not mere intelligence, to be successful or to avoid destruction.
