Scripture is the key that unlocks Scripture. The suppositions of men are worthless. Great care is to be exercised, lest human fallacies be brought in. Every student is to be educated to give a clear exposition of the Word, according to the example Christ has given in His teaching. He said nothing to gratify curiosity or to stimulate selfish ambition. He did not deal in abstract theories, but in that which is essential to the development of character, that which will enlarge man’s capacity for knowing God, and increase his power to do good. He spoke of those truths that relate to the conduct of life, and that unite man with eternity. We read that the common people heard Him gladly. The people “were astonished at his doctrine: for his word was with power” (Luke 4:32).
We need not tax our minds for some farfetched explanation of the words of Scripture. Thus the Jewish teachers did. They quoted the ideas and traditions of the rabbis, confusing the minds of their hearers. They taught for doctrine the commandments of men. We are not to seek for revelations that have not been made in the Word of God. In the simplicity of Christ we are to present the plain teaching of the Bible. Men in high positions of trust in the world will be charmed by a plain, straightforward, scriptural statement of truth.
I have been instructed that the churches have not been advancing in a knowledge of the truth for this time, but that if the teachers of truth will take up the work clearly marked out in the Scriptures, the feet of many will be planted firmly on the platform of eternal truth. Many will know more than ever before of the truth that has been given for these last days...
Let every step taken be a step of advancement toward genuine conversion, toward unreserved consecration of heart, mind, soul, and strength to the service of the Lord. Let all that is done tend to genuine reformation in thought, in word, in deed, in character building. Let the true be discerned from the false. Do not allow the enemy to lead you to weave wrong figures into the pattern. Keep the love of Christ prominent before the children and youth. Repeat to them often His simple lessons.—Letter 111, March 13, 1904, to Elder G. I. Butler, at the time president of the Southern Union.
