"Your self-confidence has been very great. No sooner has a brother been suggested to lead the meetings, or to take a position of trust in preference to yourself, than you have resolved that he should not succeed if you could help it, and with the might of your perverse will you have set your spirit to oppose. 4T 333.3"
"Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits."
