A. G. Daniells, GC President at the 1905 GC Session

Who can tell why 720 of our ministers should

be located in America, among one-twentieth of

the world’s population while only 240 of our

ministers are sent forth to work for the other

nineteen-twentieths? What good reason can be

given for spending annually $536,302.76 tithes

among seventy-five millions, and only

$155,516.57 among 1,400 millions of the

world’s perishing? We rejoice that we are able

to name so many lands in which we have

opened missions; but we

A. G. Daniells, GC President at the 1905 GC Session

deeply regret that in so many of them our

laborers are so few, and our efforts are so

feeble. We should materially strengthen our

missions in Nyasaland [Malawi], Rhodesia

[Zimbabwe], China, Korea, Ceylon [Sri Lanka],

Turkey, and Egypt. We should not delay longer

to enter such lands as the Philippines,

Madagascar, Greece, Uganda, and Persia. All

that started this movement at the beginning,

and has urged it onward to its present position,

urges us with increasing

A. G. Daniells, GC President at the 1905 GC Session

emphasis to press on, until this

gospel of the kingdom shall be

proclaimed in all the world for a

witness unto all nations. Then

and and not till then, will the end

come, for which we so earnestly

long.
