It is not alone those who openly reject the Testimonies, or who cherish doubt concerning them, that are on dangerous ground. To disregard light is to reject it. 5T 680.2
“Some of you in words acknowledge reproof, but you do not in heart accept it. You go on the same as before, only being less susceptible to the influence of the Spirit of God, becoming more and more blinded, having less wisdom, less self-control, less moral power, and less zeal and relish for religious exercises; and, unless converted, you will finally yield your hold upon God entirely. You have not made decided changes in your life when reproof has come, because you have not seen and realized your defects of character and the great contrast between your life and the life of Christ.” “What do your prayers amount to while you regard iniquity in your hearts? Unless you make a thorough change, you will, not far hence, become weary of reproof, as did the children of Israel; and, like them, you will apostatize from God.” [Testimonies for the Church 4:332 (1879).] 5T 680.3
“Many are going directly contrary to the light which God has given to His people, because they do not read the books which contain the light and knowledge in cautions, reproofs, and warnings. The cares of the world, the love of fashion, and the lack of religion have turned the attention from the light God has so graciously given, while books and periodicals containing error are traveling all over the country. Skepticism and infidelity are increasing everywhere. Light so precious, coming from the throne of God, is hid under a bushel. God will make His people responsible for this neglect. An account must be rendered to Him for every ray of light He has let shine upon our pathway, whether it has been improved to our advancement in divine things or rejected because it was more agreeable to follow inclination.” [Testimonies for the Church 4:391 (1880).] 5T 681.1
“The volumes of Spirit of Prophecy, [The Great Controversy] and also the Testimonies, should be introduced into every Sabbathkeeping family, and the brethren should know their value and be urged to read them. It was not the wisest plan to place these books at a low figure and have only one set in a church. They should be in the library of every family and be read again and again. Let them be kept where they can be read by many.” [Testimonies for the Church 4:390 (1880).] 5T 681.2
Let ministers and people remember that gospel truth hardens when it does not save. The rejection of light leaves men captives, bound about by chains of darkness and unbelief. “The soul that refuses to listen to the invitations of mercy from day to day can soon listen to the most urgent appeals without an emotion stirring his soul. As laborers with God we need more fervent piety and less self-exaltation. The more self is exalted, the more will faith in the Testimonies of the Spirit of God be lessened.... Those who trust wholly in themselves will see less and less of God in the Testimonies of His Spirit.” [Testimonies for the Church 5:134 (1882).] 5T 681.3
