Marie Tiller taught the lesson from The Teachings of Joseph Smith manual entitled, "Gaining Knowledge of Eternal Truths".
We discussed the different kinds of knowledge and how through the power of the Holy Ghost we can receive knowledge that is based on truth.
The Prophet Joseph Smith “loved learning,” wrote George Q. Cannon. “He loved knowledge for its righteous power. Through the tribulations which had surrounded him from the day when first he made known to a skeptical world his communion with the heavens, he had been ever advancing in the acquisition of intelligence. The Lord had commanded him to study, and he was obeying. … His mind, quickened by the Holy Spirit, grasped with readiness all true principles, and one by one he mastered these branches and became in them a teacher.”
Joseph Smith had a rudimentary school education, but he was taught by the Lord and by the spirit and gained a tremendous amount of knowledge.
“Mormonism is truth; and every man who embraces it feels himself at liberty to embrace every truth: consequently the shackles of superstition, bigotry, ignorance, and priestcraft, fall at once from his neck; and his eyes are opened to see the truth, and truth greatly prevails over priestcraft. …
“… Mormonism is truth, in other words the doctrine of the Latter-day Saints, is truth. … The first and fundamental principle of our holy religion is, that we believe that we have a right to embrace all, and every item of truth, without limitation or without being circumscribed or prohibited by the creeds or superstitious notions of men, or by the dominations of one another, when that truth is clearly demonstrated to our minds, and we have the highest degree of evidence of the same.”
