Jesus is not tame, but he is good.

Here's Paul Gardner on Revelation 1:

In a modern church which spends much time encouraging Christians to regard Jesus as ‘friend and brother’, this passage reminds us that if the Son of Man appeared to us right now we would fall at his feet before his glory – and until he picked us up, we would surely be fearful. Scripture never compromises the glory and majesty of Christ, while also describing him as one of us. It is all too easy to forget his ‘majesty’. … We should at one at the same time stand in awe of who he is, the one who holds the keys of death and Hades, and yet also enjoy the love and care and comfort of Jesus our friend and brother.” (Page 26)

Or, here is C S Lewis in The Lion, the Witch and the Wardrobe, page 75:

“Is — is he 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.”

Which is where Revelation chapter 1 is designed to get us, and the right way for any true Christian to feel about their Lord Jesus. Utterly terrified at the thought of meeting him, and yet wanting nothing more than the chance to do just that.

If we feel no fear at the thought of meeting Christ, it's not the biblical Christ that we're contemplating meeting. But if that fear is where we stay, if we've never felt his hand our shoulder saying, “Do not fear,” then we’ve also never met him in his grace and peace.

The wonderful news of the Christian gospel is that this Christ, this risen, glorious Christ, wants to lift us to our feet to worship him, to know him, and to serve him in the world, while we wait for the day when he comes again.
