We should exert all the powers of the mind in the study of the Scriptures, and should task the understanding to comprehend, as far as mortals can, the deep things of God; yet we must not forget that the docility and submission of a child is the true spirit of the learner. Scriptural difficulties can never be mastered by the same methods that are employed in grappling with philosophical problems. We should not engage in the study of the Bible with that self-reliance with which so many enter the domains of science, but with a prayerful dependence upon God, and a sincere desire to learn his will. We must come with a humble and teachable spirit to obtain knowledge from the great I AM. Otherwise, evil angels will so blind our minds and harden our hearts that we shall not be impressed by the truth. TSS 121.1
Many a portion of Scripture which learned men pronounce a mystery, or pass over as unimportant, is full of comfort and instruction to him who has been taught in the school of Christ. One reason why many theologians have no clearer understanding of God's word is, they close their eyes to truths which they do not wish to practise. An understanding of Bible truth depends not so much on the power of intellect brought to the search as on the singleness of purpose, the earnest longing after righteousness. TSS 121.2
The Bible should never be studied without prayer. The Holy Spirit alone can cause us to feel the importance of those things easy to be understood, or prevent us from wresting truths difficult of comprehension. It is the office of heavenly angels to prepare the heart so to comprehend God's word that we shall be charmed with its beauty, admonished by its warnings, or animated and strengthened by its promises. We should make the psalmist's petition our own, “Open Thou mine eyes, that I may behold wondrous things out of thy law.” Temptations often appear irresistible because, through neglect of prayer and the study of the Bible, the tempted one cannot readily remember God's promises and meet Satan with the Scripture weapons. But angels are round about those who are willing to be taught in divine things; and in the time of great necessity, they will bring to their remembrance the very truths which are needed.—The Great Controversy, 599.
