O Thou, God of all long desirous...

O Thou, God of all long desirous roaming, Our hearts are sick of fruitless homing, And crying after lost desire. Hearten us onward! as with fire Consuming dreams of other bliss. The best Thou givest, giving this Sufficient thing -- to travel still Over the plain, beyond the hill, Unhesitating through the shade, Amid the silence unafraid, Till, at some sudden turn, one sees Against the black and muttering trees Thine altar, wonderfully white, Among the Forests of the Night.
