TDG 166.3
(This Day With God 166.3)
God has given us a perfect, faultless pattern. God designed to make of you an able, efficient workman. The mind He designed should be purified, elevated, ennobled. If the mind is allowed to be exercised with small things, it will be feeble as the result of unchanging laws. God wants His servants to enlarge the scope of their thoughts and plans of labor and bring their powers into vigorous contact with things that are grand, elevating, ennobling. This will give new springs to the intellectual faculties. His thoughts will take broad scope and he will gird up his energies for the task of a broader, deeper, grander work, swimming in deep and broad waters where there is no bottom or shore....
