The real man has his being in Spirit, and hence his state of being is spiritual. His welfare depends upon spiritual ideas alone, and his true substance is included in infinite Mind.
Spiritual man does not have and cannot have a material estate. Humanly, we often think of an estate as an accumulation of materially valuable things, such as money, stocks and bonds, jewels, real estate, and other assets. But are these material possessions lasting, eternal, real in the absolute sense? Do they constitute man's true estate?
Christ Jesus taught that material possessions are not true riches and have no real substance. In the Sermon on the Mount, the sublime summary of his teaching, so important not only for those who listened then, but also for all his followers for all time, the Master said (Matt. 6:19), "Lay not up for yourselves treasures upon earth," and then a little later on he added this positive command, "Seek ye first the kingdom of God, and his righteousness."
