Time is short. Opportunities, though multiplying with every passing hour, will not recur, some for yet another century, others never again. However severe the challenge, however multiple the tasks, however short the time, however sombre the world outlook, however limited the material resources of a hard-pressed adolescent community, the untapped sources of celestial strength from which it can draw are measureless in their potencies, and will unhesitatingly pour forth their energizing influences if the necessary daily effort be made and the required sacrifices be willingly accepted.
