Letter to the Saints in Libery Jail

In the letter penned by the Prophet Joseph Smith in Liberty Jail, there is one quote that I think could have been canonized -

"Thy mind, O man! if thou wilt lead a soul unto salvation, must stretch as high as the utmost heavens, and search into and contemplate the darkest abyss, and the broad expanse of eternity—thou must commune with God. How much more dignified and noble are the thoughts of God, than the vain imaginations of the human heart! None but fools will trifle with the souls of men."

In very simple terms, we must be taught by the power of the Holy Ghost.
