"I daresay that in the [premortal] spirit world, when it was proposed to us to come into this probation, and pass through the experience that we are now receiving, it was not altogether pleasant and agreeable; the prospects were not so delightful in all respects as might have been desired. Yet there is no doubt that we saw and understood clearly there that, in order to accomplish our exaltation and glory, this was a necessary experience; and however disagreeable it might have appeared to us, we were willing to conform to the will of God, and consequently we are here.
The Lord has determined in His heart that He will try us until He knows what He can do with us. He tried His Son Jesus. … Before He [the Savior] came upon earth the Father had watched His course and knew that He could depend upon Him when the salvation of worlds should be at stake; and He was not disappointed. So in regard to ourselves. He will try us, and continue to try us, in order that He may place us in the highest positions in life and put upon us the most sacred responsibilities."
