"I am saying that out of a spirit of appreciation and gratitude, and a sense of duty, you ought to make whatever adjustment is necessary to give a little of your time-as little as two years-consecrating your strength, your means, your talents to the work of sharing with others the gospel, which is the source of so much of the good that you have. I promise that if you will do so, you will come to know that what appears today to be a sacrifice will prove instead to be the greatest investment that you will ever make."
