One of the grandest things in having rights is, that though they are your rights, you may give them up.
from A Dictionary of Thoughts: Being a Cyclopedia of Laconic Quotations from the Best Authors, Both Ancient and Modern by Tryon Edwards, D.D.
Thanks to Tom Pedersen for bringing this quote to my attention.
If you who set yourselves to explain the theory of Christianity, had set yourselves instead to do the will of the Master, the one object for which the Gospel was preached to you, how different would now be the condition of that portion of the world with which you come into contact! Had you given yourselves to the understanding of his word that you might do it, and to be the quarrying of material wherewith to buttress your systems, in many a heart by this time would the name of the Lord be loved where not it remains unknown.
George McDonaold, quoted in Habits of the Mind by James W. Sire
