As a rule, the more thoroughly disciplined and fit a man may be for any
really great work, the more conscious will he be of his own unfitness
for it, the more distrustful of himself, the more anxious not to thrust
himself forward. It is only the zeal of the half-instructed when the
hour of a great deliverance has come at last—of those who have had a
glimpse of the glory of the goal, but have never known or counted the
perils of the path which leads to it—which is ready with the prompt
response, “Yes—we can drink of the cup, we can be baptized with the
baptism.”
