Or at least that’s what we’re told in Prince Caspian. The truth is, however, slightly different. It is true that for the third story only Edmund and Lucy return. All four return for A Horse and His Boy and three of them return for The Last Battle.
What I believe Aslan is trying to say is that the two older ones have learned all they are going to for now, and the next adventure will be for the younger. (I’m actively reading the books now with the little ones so I’ll let you know…)
Suffice it to say, each believer has a chosen path, different gifts and talents, different things that they will be called on to do– and different experiences. We can’t all expect to be like Elijah or Joshua of the Bible days. We can’t believe that God wants all of us to tell the Sun to stand still, to call fire down from Heaven, or to never taste death.
What we can expect, however, is that the God of these Old and New Testament saints is the same God of today– He is still at work, He still has a plan, and He’s still calling us to join Him in the work.
