We cannot always do what we would like to do, but we shall have the power to do that which we should do. The Lord will give us the power to do this. (Teachings of Presidents of the Church: Lorenzo Snow, Chapter 11: “I Seek Not Mine Own Will, but the Will of the Father”) We depend upon God; and in all our works and labors, and in all the success that attends us in our labors, we feel that it has been God who has wrought it.
