Every man, of whatever trade or profession, should make the cause of God his first interest; he should not only exercise his talents to advance the Lord's work, but should cultivate his ability to this end. Many a man devotes months and years to the acquirement of a trade or profession that he may become a successful worker in the world; and yet he makes no special effort to cultivate those talents which would render him a successful laborer in the vineyard of the Lord. He has perverted his powers, misused his talents. He has shown disrespect to his heavenly Master. This is the great sin of the professed people of God. They serve themselves, and serve the world. They may have the name of being shrewd, successful financiers; but they neglect to increase by use the talents which God has given them for His service. The worldly tact is becoming stronger by exercise; the spiritual is becoming weaker through inactivity.—The Review and Herald, January 1, 1884. CS 124.1
