The highest secret of Bible study is that teachable spirit which is inseparable from obedience…. Our Lord says, “If any man will do His will He shall know of the doctrine” (John 7.17); in other words, obedience is the organ of the spiritual revelation. Insight into the Scriptures is never independent of the obedient frame, but is conditioned upon actual conformity to their precepts and sympathy with their spirit. True biblical learning is not so much mental as experimental. There are professed teachers and preachers who no more grasp the truth they nominally hold than does a sparrow grasp the message that passes through the telegraph wife on which it perches.”
