The three great principles taught by the Holy Spirit in a time of His mighty working,—
that the Church exists only for extending the kingdom,
that every member must be trained to take part in it, and
that the personal experience of the love of Christ is the power that fits for this: to these principles the Brethren have remained true, and it is in this respect that their example speaks to us with such power.
Andrew Murray, The Key to the Missionary Problem (London: J. Nisbet & Co., 1902), 66.
