In 2 Chronicles 18:21, the Bible tells us that a lying spirit was in the mouths of the prophets to cause them to utter lies. That spirit hasn't died, and because what he did worked, there're other spirits who do the same today. They take over people and make them utter lies without restraint.

 

That's why it's important that you test every spirit; don't just believe everything; believe only that which is true, honest, just, pure, lovely, of good report, virtuous, and praise-worthy. Don't believe a rumour; like some would say, "In every rumour, there's an element of truth". How could there be an element of truth in a rumour founded on falsehood? What element of truth was there when they lied against Jesus? The Bible says they hated Him without a cause, and lied against Him (Matthew 26:59).

 

Such things still happen today! There're still lying spirits. It's the same devil; he has no new tricks. His strategies are the same. If he could be a lying spirit in the mouths of prophets in the Old Testament, you can imagine what he could be in, and do with, those who let him.

 

He can be a lying spirit in the mouth of children against their parents, or vice versa. He could be a lying spirit in the mouth of a friend or family member against another friend or other family members. He's just that way; he's Satan; the deceiver and manipulator. However, we're not ignorant of his devices.

 

Follow God's Word, and allow the Holy Spirit guide you in all things; He's the Spirit of truth, and He alone can guide you in the path of truth always.
