In the Lion, the Witch and the Wardrobe there's a famous exchange between Mr. Beaver, Lucy Pevensie, Susan Pevensie and Mrs. Beaver. When Susan asks if Aslan the Lion is safe, Mr. Beaver responds:

"Safe?" said Mr Beaver ..."Who said anything about safe? 'Course he isn't safe. But he's good. He's the King, I tell you.”

Aslan the Lion is the most dangerous creature in all of Narnia. And that's good. Because HE is good--and he's the king.

What does it mean that Aslan isn't safe? How can he be dangerous and good at the same time? Find out in this video.
