Okay kiddo,
So in Revelation 5, we learn about a special book that contains important information about what is going to happen in the future.
But here is the thing... Nobody can open this book!
Everyone becomes sad because nobody can find out what is inside, but then a special person comes along. This person is named the "Lion of Judah".
But wait! When we look closer, we see that he isn't a real lion, but instead he is Jesus. Jesus is the person who can open the special book!
Everyone cheers and sings songs of praise! Jesus is really amazing, don't you think?
That's pretty much what happens in Revelation 5. It's a special chapter in the Bible that talks about how only Jesus is able to reveal what will happen in the future.
