“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.”
-C.S. Lewis, The Lion, the Witch, and the Wardrobe
If indeed we follow one whose natural life ended hanging on a cross, then being safe should not be among our priorities. But I, for one, view being safe as reasonably prudential, if not totally faithful.
