The creator and his creations

(On seeing the soul-stirring picture of President Kennedy in his office, clapping, Caroline and John dancing.
)

Who says doleful is God's Creation vast?
Kennedy and his snow-white creations find
Ecstasy within, ecstasy without, to outlast
The world's tenebrous throes naked and blind.

Behold, the face of all the world is changed,
The sky of hopes within her core arranged.
