The header for this post is a quotation of Hebrews 10:31 in the English Standard Verson.  When I read that verse I was reminded of the words exchanged by Mr. and Mrs. Beaver and the Pevensie children in CS Lewis' The Lion, the Witch, and the Wardrobe:

"Is — is [Aslan] a man?" asked Lucy.

"Aslan a man!" said Mr. Beaver sternly.

"Certainly not. I tell you he is the King of the wood and the son of the great Emperor-Beyond-the-Sea. Don't you know who is the King of Beasts? Aslan is a lion — THE Lion, the great Lion."

"Ooh!" said Susan. "I'd thought he was a man. Is he — quite safe? I shall feel rather nervous about meeting a lion."

"That you will, dearie, and no mistake," said Mrs. Beaver, "if there's anyone who can appear before Aslan without their knees knocking, they're either braver than most or else just silly."

"Then he isn't safe?" said Lucy.

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

"I'm longing to see him," said Peter, "even if I do feel frightened when it comes to the point."

I think that is a very depiction of what we will feel when we face God.  Thankfully, however, those who trust in Christ have nothing to fear.
