Knowledge is the source of Wealth. Applied to tasks we already know, it becomes Productivity. Applied to tasks that are new, it becomes Innovation.
Our lives are full of supposes. Suppose this should happen, or suppose that should happen; what could we do; how could we bear it? But, if we are living in the high tower of the dwelling place of God, all these supposes will drop out of our lives. We shall be quiet from the fear of evil, for no threatenings of evil can penetrate into the high tower of God.
