USBN #154 July 1942 p3
" Perhaps the reason why you have not accomplished so much in the field of teaching is the extent you have looked upon your own weaknesses and inabilities to spread the Message. Baha'u'llah and the Master have both urged us repeatedly to disregard our own handicaps and lay our whole reliance upon God. He will come to our aid if we only arise and become an active channel for God's Grace.
"Do you think it is the teachers who make converts and change human hearts? No, surely not. They are only pure souls who take the first steps and then let the spirit of Baha'u'llah move and make use of them . If any one of them should even for a second think, or consider his achievements as due to his own capacities, his work is ended and his fall starts . This is the fact why so many competent souls have, after wonderful services, suddenly found themselves utterly impotent and perhaps thrown aside by the spirit of the Cause as useless souls. The criterion is the extent to which we are ready to have the will of God work through us."
to Mrs. Marie Hopper on October 26, 1933.
