The phrase, “further up and further in,” comes from C. S. Lewis’ final book of his Narnia series in which the storyline heads toward a grand conclusion and a heavenly habitation. The phrase itself should be understood as a summons. It is a call to keep one’s eyes ever on goal that awaits us: union with God. It is God who stands up on the mountain and calls us to himself. And until we arrive at that place, we will always be “sojourners and exiles”, as 1 Peter puts it. We are midway through a journey that will take us past death and into life. We are called to higher things. And so as we journey on, there is always further up and further in.
