God requires the training of the mental faculties. He designs that His servants shall possess more intelligence and clearer discernment than the worldling, and He is displeased with those who are too careless or too indolent to become efficient, well-informed workers. The Lord bids us love Him with all the heart, and with all the soul, and with all the strength, and with all the mind. This lays upon us the obligation of developing the intellect to its fullest capacity, that with all the mind we may know and love our Creator. MYP 173.1
If placed under the control of His Spirit, the more thoroughly the intellect is cultivated the more effectively it can be used in the service of God. The uneducated man who is consecrated to God and who longs to bless others can be, and is, used by the Lord in His service. But those who, with the same spirit of consecration, have had the benefit of a thorough education, can do a much more extensive work for Christ. They stand on vantage ground. MYP 173.2
