"The Bible with its precious gems of truth was not written for the scholar alone. On the contrary, it was designed for the common people; and the interpretation given by the common people, when aided by the Holy Spirit, accords best with the truth as it is in Jesus. The great truths necessary for salvation are made clear as the noonday, and none will mistake and lose their way except those who follow their own judgment instead of the plainly revealed will of God." {5T 331.2}
"But God will have a people upon the earth to maintain the Bible, and the Bible only, as the standard of all doctrines and the basis of all reforms. The opinions of learned men, the deductions of science, the creeds or decisions of ecclesiastical councils, as numerous and discordant as are the churches which they represent, the voice of the majority--not one nor all of these should be regarded as evidence for or against any point of religious faith. Before accepting any doctrine or precept, we should demand a plain "Thus saith the Lord" in its support." {GC 595.1}

NotebookLM gives wrong answers if only the bible is added as a source because of all the wrong things in the internet that was used to train the language model. That's why God sends prophets (tested by scripture), to help keep "alignment".
