"And the Spirit of the Lord shall rest upon him, the Spirit of wisdom and understanding." Isaiah 11:2
"'Be babes in evil, but in thinking be mature' (1 Cor. 14:20). It is not easy to be a leader of people who can out-think you. A leader must be one who, when he sees a set of circumstances, thinks about it. He sits down with pad and pencil and doodles and writes and creates. He tests all things with his mind and holds fast to what is good (1 Thess. 5:21). He is critical in the best sense of the word, that is, not gullible or faddish or trendy. He weighs things and considers pros and cons and always has a significant rationale for the decisions that he makes. Careful and rigorous thought is not contrary to a reliance on prayer and divine revelation. The apostle Paul said to Timothy in 2 Timothy 2:7, 'Think over what I say, for the Lord will grant you understanding in everything.' In other words, God's way of imparting to us insight is not to short-circuit the intellectual process."
John Piper, "Marks of a Spiritual Leader," #7, A Hard Thinker
"People who are in a hurry to get out of the university and start earning money or serving the church or preaching the gospel have no idea of the infinite value of spending years of leisure conversing with the greatest minds and souls of the past, ripening and sharpening and enlarging their powers of thinking. The result is that the arena of creative thinking is vacated and abdicated to the enemy."
Charles Malik, "The Other Side of Evangelism," Christianity Today, 7 November 1980, page 40.
"In our quest for the fullness of the Spirit, we have sometimes forgotten that a Spirit-filled intelligence is one of the powerful weapons for pulling down satanic strongholds."
