The written testimonies are not to give new light, but to impress vividly upon the heart the truths of inspiration already revealed. Man's duty to God and to his fellow man has been distinctly specified in God's word, yet but few of you are obedient to the light given. Additional truth is not brought out; but God has through the Testimonies simplified the great truths already given and in His own chosen way brought them before the people to awaken and impress the mind with them, that all may be left without excuse. The Testimonies are not to belittle the word of God, but to exalt it and attract minds to it, that the beautiful simplicity of truth may impress all.117Testimonies for the Church 5:665 CCh 92.1
The Spirit was not given—nor can it ever be bestowed—to supersede the Bible; for the Scriptures explicitly state that the word of God is the standard by which all teaching and experience must be tested. Says the apostle John, “Believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.” 1 John 4:1. And Isaiah declares, “To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.” Isaiah 8:20.118The Great Controversy vii. CCh 92.2
Brother J would confuse the mind by seeking to make it appear that the light God has given through the Testimonies is an addition to the Word of God, but in this he presents the matter in a false light. God has seen fit in this manner to bring the minds of His people to His word, to give them a clearer understanding of it. The word of God is sufficient to enlighten the most beclouded mind and may be understood by those who have any desire to understand it. But notwithstanding all this, some who profess to make the Word of God their study are found living in direct opposition to its plainest teachings. Then, to leave men and women without excuse, God gives plain and pointed testimonies, bringing them back to the word that they have neglected to follow. The word of God abounds in general principles for the formation of correct habits of living, and the testimonies, general and personal, have been calculated to call their attention more especially to these principles. CCh 92.3
I took the precious Bible and surrounded it with the several Testimonies for the Church, given for the people of God. Here, said I, the cases of nearly all are met. The sins they are to shun are pointed out. The counsel that they desire can be found here, given for other cases situated similarly to themselves. God has been pleased to give you line upon line and precept upon precept. CCh 92.4
But there are not many of you that really know what is contained in the Testimonies. You are not familiar with the Scriptures. If you had made God's Word your study, with a desire to reach the Bible standard and attain to Christian perfection, you would not have needed the Testimonies. It is because you have neglected to acquaint yourselves with God's inspired Book that He has sought to reach you by simple, direct testimonies, calling your attention to the words of inspiration which you had neglected to obey, and urging you to fashion your lives in accordance with its pure and elevated teachings.119Testimonies for the Church 5:663-665 CCh 92.5
