I believe that God really has dived down into the bottom of creation, and has come up bringing the whole redeemed nature on His shoulders. The miracles that have already happened are, of course, as Scripture so often says, the first fruits of that cosmic summer which is presently coming on. Christ has risen, and so we shall rise.

…To be sure, it feels wintry enough still: but often in the very early spring it feels like that. Two thousand years are only a day or two by this scale. A man really ought to say, ‘The Resurrection happened two thousand years ago’ in the same spirit in which he says ‘I saw a crocus yesterday.’

Because we know what is coming behind the crocus.

The spring comes slowly down the way, but the great thing is that the corner has been turned. There is, of course, this difference that in the natural spring the crocus cannot choose whether it will respond or not. We can. We have the power either of withstanding the spring, and sinking back into the cosmic winter, or of going on…to which He is calling us.

It remains with us whether to follow or not, to die in this winter, or to go on into that spring and that summer.

-C. S. Lewis, God in the Dock
