Chemists who are familiar with analyzing matter, inform you that the globe we inhabit is composed of small particles, so small that they cannot be seen with the unaided natural eye, and that one of these small particles may be divided into millions of parts, each part so minute as to be indiscernible by the aid of the finest microscopes. So the walk of man is made up of acts performed from day to day. It is the aggregate of the acts which I perform through life that makes up the conduct that will be exhibited in the day of judgment, and when the books are opened, there will be the life which I have lived for me to look upon, and there also will be the acts of your lives to look upon. Do you not know that the building up of the Kingdom of God, the gathering of Israel, is to be done by little acts? You breathe one breath at a time; each moment is set apart to its act, and each act to its moment. It is the moments and the little acts that make the sum of the life of man. Let every second, minute, hour, and day we live be spent in doing that which we know to be right.
